adjust the do-compat-* rules now that src/compat/lib and friends no longer exist

Support "extsrc", externally added programs and libraries.  Users can write
their own reach-overs, cross-build, install, and get set files just like base
and X11 / X.org.  (These sets are not included as TNF releases.)

build & install librumpdev_netsmb and librumpfs_smbfs components

Let us use MKKMOD=yes to leave the kernel modules out of the
distribution.

Build modules before rump libs so that something else can be
unwarrantedly blamed for a change.

This commit follows the style guide and is entirely non-build-tested.

add crypto/external to the build.

Pull up pkg_install-20090528, libarchive-2.5.5 and libfetch-2.23
with the associated build infrastructure as of 20090929 from HEAD.

Apply patch (requested by joerg in ticket #1322):

Sync with HEAD.

Third (and last) commit. See http://mail-index.netbsd.org/source-changes/2009/05/13/msg221222.html

Make clean_METALOG in distrib/sets early in the build, to ensure that
the METALOG does not grow without bounds on multiple MKUPDATE builds.
(Previously, sanitise_METALOG in distrib/sets/Makefile used to do
something like this near the end of a build.)

Remove an explicit BUILDTARGETS do-compat-external-lib before do-build
because now src/compat/Makefile descends there and no particular
dependency on 32 bit compat external libs during do-build.

Use ll instead of non-standard q as length modifier in format strings. Makes
this work on Solaris. OK by apb.
Not every grep knows -q. Ok by apb.
Use sed, awk and hexdump from tools to make this work on Solaris. Ok by apb.
Use awk and grep host tools where required.  'build.sh release' now
works on Solaris (but only with HOST_CC=/usr/sfw/bin/gcc for now).
"grep -q" is not portable; use "grep >/dev/null" instead.  Also add a
comment saying that postinstal is invoked during a cross build.
In file_exists_exact(), fix an incorrect test of "1" instead of "$1",
and improve the comment explaining what this function does.
As long as we don't yet have a working TOOL_GREP, fgrep is more portablethan grep -F.

Disable grep host tool and unbreak NetBSD build until I can come up with a
clean fix.

Use awk and grep host tools where required.  'build.sh release' now works
on Solaris (but only with HOST_CC=/usr/sfw/bin/gcc for now).

Add the top-level do-compat-external-lib target that mimics
do-external-lib so that we can build the compat libraries for
ATF.  Also add compat/external/lib/Makefile following the same
example of external/lib/Makefile, which descends into the
external libraries and builds them.

Build kernel modules the same time as the rest of the system libraries.

- retire MKXORG from public use

- enable 32-bit library builds on amd64 and sparc64

- add 3 new top-level targets:
    do-compat-lib-csu
    do-compat-libgcc
    do-compat-lib-libc
  and run them before "do-build" if ${MKCOMPAT} != "no"

Add a do-top-obj target, which builds the top-level obj directory.
This uses the new NOSUBDIR support in bsd.subdir.mk.

Insert do-top-obj near the beginning of BUILDTARGETS.  The first few
items are now:
    cleandir:        cleans the tree.
    do-top-obj:      creates the top level object directory.
    do-tools-obj:    creates object directories for the host toolchain.
    do-tools:        builds host toolchain.
    obj:             creates object directories.

Also improve a comment and split a long line where SUBDIR is set from
_SUBDIR.

Defer the "make obj" step until after tools are built and installed.

There may be commands embedded in "!=" assignments that depend on tools
being available, and previously these would have printed error messages
during "make obj".  They may still print error messages during "make
cleandir", which (if it is performed at all) is performed before tools
are built.

add do-sys-rump-net-lib

PR/39687 - Henning Petersen -- comment typo

Sync with wrstuden-revivesa-base-2.

Improve support for MKXORG!=no to enable builds into external/mit/xorg.
This will be mutually exclusive to MKX11!=no.

Build pcc and pcc-based crtstuff if using pcc compiler.

Install rump libraries and utilities to the base system and remove the
private non-installed build infrastructure from sys/rump.

breakdown of commit:
  * install relevant headers into /usr/include/rump
  * build sys/rump/librump/rumpuser and sys/rump/librump/rumpkern
    from src/lib and install as librumpuser and librump, respectively
    + this retains the ability to test a librump build with just the
      kernel sources at hand
  * move sys/rump/fs/lib/libukfs and sys/rump/fs/lib/libp2k to src/lib
    for general consumption, they are not kernel-space dwellers anyway
  * build and install sys/rump/fs/lib/lib$fs as librumpfs_$fs
  * add chapter 3 manual pages for rump, rumpuser, ukfs and p2k
  * build and install userspace kernel file system daemons if MKPUFFS=yes
    is spexified
  * retire fsconsole for now, it will make a comeback with an actually
    implemented version shortly

if MKXORG != no, use external/mit/xorg subdir instead of x11 subdir for
the mk-x11 target.

Add the tests.tgz set

This adds a new tests.tgz set to releases which includes all the tests
for the system.  It is important to note that this set does not rely on
comp.tgz: a user of the system can run the tests without having the
development tools installed, which can be useful in a production machine.

Add an iso-dir=directory option.  When combined with iso-image or
iso-image-source, it will cause directory to be added to the CD-ROM image.

Convert build.sh iso-dir=directory option to -C cddir as per jmmv@ on
source-changes.

Provide 'do-libgcc' to build gnu/lib/crtstuff${LIBGCC_EXT} (if necessary)
and then gnu/lib/libgcc${LIBGCC_EXT}.
Makes it easier to cut&paste from the list of targets built with 'make build'.

Add an iso-image-source option which does the same thing as iso-image but
includes source sets as well.  The infrastructure for this was already
there, although it needed a bug fix.  Will look at adding arbitrary
directories next.

Improve the use of makefs to build boot CDs, and make it truely MI:
- allow to specify the "instkernel" directory, and allow to put multiple
  kernels on the image
- allow to specify the directory where the image will be created
- only use bootxx_cd9660 if it exists
- search for second-stage boot as usr/mdec/boot.${MACHINE} in addition to
  usr/mdec/boot
- make 'installboot -e' optional
- use target 'release' or 'iso_image' depending on ${CDRELEASE}
- call some MD targets, which will eventually complete the file list or
  make the image bootable
For the benefit of modern hardware, enable ACPI by default in INSTALL and
GENERIC kernels. If ACPI is an issue on your hardware, 'boot -c' and
'disable acpi' should be a workaround. ACPI-enabled kernels works fine
on pre-acpi hardware.
for amd64:
- add ACPI to INSTALL and GENERIC, remove the *_ACPI config files.
- get rid of the bootfloppy-big.fs boot image, and got to a 3-floppy boot
  image
for i386:
- introduce INSTALL_LARGE which has ACPI and some devices with big firmware
- move some devices from INSTALL to INSTALL_LARGE
- Boot floppies still use INSTALL, and bootfloppy-big.fs is still there
  (for thoses who want to build el-torito floppy emulation boot CD) and use
  INSTALL.
For both, drop the 'iso-image' code in etc/ to make the iso bootable, we'll
use something else to build bootable CDs.
Add an iso_image target (iso-image as a target name doesn't play well with
bsd.subdirs.mk) in distrib/makefile, which builds an iso image for $MACHINE
with binary sets, stored in ${RELEASEDIR}/iso. The image is bootable for:
alpha, amd64, cats, i386, pmax, sgimips, sparc, sparc64, sun3, vax.
mac68k/macppc no there yet because of missing feature in makefs.
call iso_image in distrib/ for iso-image in the top Makefile.
Use the new common/Makefile.bootcd to make i386 and amd64 bootable ISO
images. amd64 gets a single kernel; i386 images gets 3 kernels:
- netbsd, copy from netbsd-INSTALL_LARGE.gz, loaded by default
- nbsd-l, copy from netbsd-INSTALL_LAPTOP.gz
- nbsd-i, copy from netbsd-INSTALL.gz for those who want the traditionnal
  non-ACPI kernel
- drop the bootcd-laptop image
both gets an installcd image, which is the same as bootcd but with the
binary sets in addition to kernels.
Make iso-image do nothing for all but mac68k, which still
relies on mkisofs to create bootable ISO image. macppc should also be there,
but it seems the code to make an iso bootable never got added in etc.macppc/
Fix typo in subdir name.
Revert local changes that went in accidentally with the "add ACPI" commit.
Note ACPI by default in i386/amd64, and the iso-image changes.
Fix SUBDIR in previous
Remove duplicate ACPIVERBOSE and ACPI_SCANPCI; pointed out by Nicolas Joly.
Correct typo: the directory is named cdroms, not cdrom.
Use nblaptop and nbnoacpi for the alternative kernel names; as suggected by
Alan Barrett. While there factor out the kernels in Makefile.cdrom.

Add an iso_image target (iso-image as a target name doesn't play well with
bsd.subdirs.mk) in distrib/makefile, which builds an iso image for $MACHINE
with binary sets, stored in ${RELEASEDIR}/iso. The image is bootable for:
alpha, amd64, cats, i386, pmax, sgimips, sparc, sparc64, sun3, vax.
mac68k/macppc no there yet because of missing feature in makefs.

call iso_image in distrib/ for iso-image in the top Makefile.

don't filter out .WAIT when converting from _SUBDIR to SUBDIR

remove support for building (with) GCC 2.95.  also:
- always install <stdbool.h>
- don't generate a fake one for vax / gettext.

retire HAVE_GCC3/HAVE_GCC4 and introduce HAVE_GCC that is set to 2, 3 or 4.

* Add an "iso-image" target in the top level Makefile,
  which invokes make iso-image in the etc directory.
* Add an "iso-image" action in build.sh, which
  invokes make iso-image.
* Document the above in doc/BUILDING.mdoc.
* Re-generate BUILDING.

Approved by christos

Add .MAKE to all targets that use ${MAKEDIRTARGET} otherwise make closes
the job-token pipe and the sub-makes have their own '-j n' processes.
As well as giving unexpected parallelism, it makes it impossible to stop

        - creates libgcc, libgcc_eh and libgcc_s

          There's a hack in here at the moment with respect to libgcc_so in that it
          is preferable to link against libgcc_so will only when -shared-libgcc is
          specified (the c++ frontend does this automatically.) Configurations where
          LINK_EH_SPEC is defined already do this. The gcc configuration for
          NetBSD/alpha and another NetBSD platform (I forget which) actually define
          LINK_EH_SPEC probably by accident rather than design.

        - updates share/mk to use the compiler's knowledge of what needs linking into
          libraries and executables. This removes an hppa hack.

        - updates the sets for the newly created libgcc* files.

grotty from groff 1.19 needs -c for -b, -o or -u to work.

This is damn annoying, because it means the old method of "groff -P-bou"
won't suppress escape codes, unless -P-c is also provided.
(Mmm, quality software...)

Add postinstall-fix-obsolete (to invoke "postinstall fix obsolete" -
funny that :), and call in "distribution" just before the "make checkflist".
Should minimise a bunch of the "I use make UPDATE= and checkflist failed"
errors, but not all of them.

Rename a large chunk of the make(1) variables which refer to a
program/tool from "FOO" to "TOOL_FOO".  The new variables are:
	TOOL_ASN1_COMPILE  TOOL_CAP_MKDB  TOOL_CAT  TOOL_CKSUM  TOOL_COMPILE_ET
	TOOL_CONFIG  TOOL_CRUNCHGEN  TOOL_CTAGS  TOOL_DB  TOOL_EQN  TOOL_FGEN
	TOOL_GENCAT  TOOL_GROFF  TOOL_HEXDUMP  TOOL_INDXBIB  TOOL_INSTALLBOOT
	TOOL_INSTALL_INFO  TOOL_M4  TOOL_MAKEFS  TOOL_MAKEINFO  TOOL_MAKEWHATIS
	TOOL_MDSETIMAGE  TOOL_MENUC  TOOL_MKCSMAPPER  TOOL_MKESDB
	TOOL_MKLOCALE  TOOL_MKMAGIC  TOOL_MKTEMP  TOOL_MSGC  TOOL_MTREE
	TOOL_PAX  TOOL_PIC  TOOL_PREPMKBOOTIMAGE  TOOL_PWD_MKDB  TOOL_REFER
	TOOL_ROFF_ASCII  TOOL_ROFF_DVI  TOOL_ROFF_HTML  TOOL_ROFF_PS
	TOOL_ROFF_RAW  TOOL_RPCGEN  TOOL_SOELIM  TOOL_SUNLABEL  TOOL_TBL
	TOOL_UUDECODE  TOOL_VGRIND  TOOL_ZIC

For each, provide default in <bsd.sys.mk> of the form:
	TOOL_FOO?=	foo
and for the ${USETOOLS}=="yes" case in <bsd.own.mk>, provide override:
	TOOL_FOO=	${TOOLDIR}/bin/${_TOOL_PREFIX}foo

Document all of these in bsd.README.

This cleans up a chunk of potential (and actual) namespace collision
within our build infrastructure, as well as improves consistency in
the share/mk documentation and provision of appropriate defaults for
each of these variables.

Rework how KERNOBJDIR functions; now it's always determined with
	cd ${KERNSRCDIR}/${KERNARCHDIR}/compile && ${PRINTOBJDIR}
This is far simpler than the previous system, and more robust with
objdirs built via BSDOBJDIR.

The previous method of finding KERNOBJDIR when using BSDOBJDIR by
referencing _SRC_TOP_OBJ_ from another directory was extremely
fragile due to the depth first tree walk by <bsd.subdir.mk>, and
the caching of _SRC_TOP_OBJ_ (with MAKEOVERRIDES) which would be
empty on the *first* pass to create fresh objdirs.

This change requires adding sys/arch/*/compile/Makefile to create
the objdir in that directory, and descending into arch/*/compile
from arch/*/Makefile.  Remove the now-unnecessary .keep_me files
whilst here.

Per lengthy discussion with Andrew Brown.

Add an obj rule to create ${KERNOBJDIR} here, at the end of the "make obj"
pass.  (etc/Makefile doesn't create this any more).

Install release files under "${RELEASEDIR}/${MACHINE}/..." instead of
"${RELEASEDIR}/...".

${RELEASEDIR} is never cleaned , and ${RELEASEDIR}/${MACHINE} is only
cleaned if UPDATE is not defined.

The obj target for src/etc is invoked too early for it to function
properly in a clean tree (bsd.subdir.mk makes the obj target in
.CURDIR depend on the recursive targets).  If "make obj" is invoked a
second time, the problem will correct itself.  To work around this:

(1) Before including bsd.subdir.mk, create a target called "obj-etc"
so that the "regular" one (from bsd.subdir.mk) won't be instantiated.

(2) After including bsd.obj.mk, create a "real" obj-etc target that
does the required work with .USE as a "source" so that we can merely
cons it onto the actual obj target.  Note that this is only done if
the obj target has commands (ie, NOOBJ was not set and MKOBJ was not
no and whatever else you might have come up with) and we would have
recursed into etc anyway (etc is in the SUBDIR list).

This makes the obj target in src/etc get invoked *after* the obj
target in the root of the source tree so that KERNOBJDIR will have the
correct value.

move BUILDING.mdoc -> doc/BUILDING.mdoc

* Eliminate the USE_NEW_TOOLCHAIN variable.  Instead, split it into
  two variables:

  TOOLCHAIN_MISSING -- set to "yes" on platforms for which there is
  no working in-tree toolchain (hppa, ns32k, sh5, x86_64).

  EXTERNAL_TOOLCHAIN -- if defined by the user, points to the root of
  an external toolchain (e.g. /usr/local/gnu).  This enables the cross-build
  framework even for TOOLCHAIN_MISSING platforms.

  If TOOLCHAIN_MISSING is set to "yes", MKGDB, MKBFD, and MKGCC are all
  unconditionally set to "no", since the bits are not there to build.

  If EXTERNAL_TOOLCHAIN is set, MKGCC is unconditionally set to "no",
  since the external toolchain's compiler is not in-sync with the
  in-tree compiler support components (e.g. libgcc).

Move the METALOG from ${_SRC_TOP_OBJ_} to ${DESTDIR}.

There were too many synchronisation problems with using the former;
including situations such as a "make clean" performed between two
installs to the same DESTDIR would result in a truncated METALOG and
the resultant sets would be missing stuff such as include files that
don't get reinstalled if they haven't changed, even with !UPDATE.

to missing dependancies can be analyzed and corrected.

move postinstall from afterinstall to separate "postinstall-check" target.
requested by Matthias Scheler <tron@zhadum.de>.

run "./etc/postinstall check" in afterinstall:

Revert previous so crtbeginS and crtendS are available.

We don't need to do "install" of lib/csu specially.  Just install it with
the rest of lib.

(None of lib/* needs csu installed in order to link.  In the USETOOLS!=yes
case, csu may even depend on a newer libc, so installing csu before
compiling host tools in lib/ could break things even worse.)

Split the _SUBDIR assignment into two assignments so you can do things
like "grep ^_SUBDIR Makefile".

Build whatis.db and infodir-meta from the commands list of the afterinstall
target. Remember: inserting `dummy' targets is not equivalent of some
convenient macro expansion; it has side effects!

Restructure infodir-meta to call a proper submake. Put the code into the
install-info gnu subdir as it's the program updating the dir file. This
all has to happen because METALOG depends on _SRC_TOP_OBJ which is now
not defined in the top level Makefile per tv's last commit. Which is fine
as this rule should have gone into a program's Makefile anyways just like
the whatis.db one does.

If _SRC_TOP_OBJ_ gets set here, we will end up with a directory that may
not be the top level objdir, because "make obj" can happen in the *middle*
of "make build" (long after <bsd.own.mk> is calculated it).  So, pre-set
_SRC_TOP_OBJ_ here so it will not be added to ${.MAKEOVERRIDES}.

Bomb if NBUILDJOBS is set, as it is badly broken in some way (as described
in toolchain/14837).  This is the root of some problems thought to be of
different causes by users who forget to say that they are using
"build.sh -j"....

remove METALOG in clean

Add a wrapper for the "distribution" target, similar to the wrapper
for the "release" target.

Add a new target (infodir-meta:) that synthesizes the share/info/dir
file's metadata if UNPRIVED and MKINFO != no. Make afterinstall depend
on it as well as whatis.db.
XXX I wish there was a more rational place to synthesize the metadata,
but I can't think of one. The share/info/dir file is built by all the
world's install-info executions.

No, really revert previous.  Recursing to etc works, and I'm in the middle
of fixing distrib right now.  If something's broken, please report it via
the proper channels.

No, really take etc and distrib out of the default subdir
list.  We've waited too long for the null target sweep.

Warn when "make build" is started with USE_NEW_TOOLCHAIN on a platform for
which USE_NEW_TOOLCHAIN is not verified to work [is not on by default].

Reverse the order of "make cleandir" and "make obj" back to the way they
were historically.  Discrepancy noted by atatat.

Rather than build in `tools' and `lib' twice, build `tools' and `lib'
completely and install them, then skip recursing into those directories
on the final dependall/install.

The top level has an objdir now, so make sure to cd to ${.CURDIR} when
recursing in-place.

Major overhaul of src/tools and host toolchain.  Summary of changes:

* Rewrite src/tools Make logic to work like the rest of the tree wrt
  "dependall" and "install".  The old "make build" hack is gone.

* Remove the MKTOOLS logic.  This was linked to the "make build" hack,
  and was only needed because TOOLDIR originally had no writable default.

* Redo the GNU configure/make logic to make it fit reasonably in a
  BSD make wrapper.  Use new ${.ALLTARGETS} variable to scan for
  targets in $(srcdir), and mark them with .MADE: to prevent rebuilding.

* Only build cross tools in src/tools; remove some messy logic in
  src/usr.* and src/gnu/usr.* that would do target filename rewriting
  (improves consistency and readability).

* Add the ability to build cross gdb at tool build time by setting
  MKCROSSGDB (default no) to "yes" in mk.conf.

* Add src/tools/groff and set up paths to work with this cross groff.

Create an objdir here for storage of timestamps, build-wide data, and so
forth.

By popular demand, one preformatted version of BUILDING, plaintext, no CRs.

Revert previous.  <bsd.own.mk> already defaults MKOBJDIRS to "no".  Also
clean up the evaluation of ${MKOBJDIRS} later -- no need for :Uno.

Add back original behavior of MKOBJDIRS defaulting to "no" so it doesn't
force people to set yet another variable to get the expected behavior

Add back logic which forces DESTDIR=/ for the distrib-dirs rule if it's not set
or it's blank. The new toolchain rules set it to blank which can run into
the sanity checks in etc/Makefile

* Always descend into "tools" regardless of USETOOLS setting.  Instead,
  just don't build the tools if USETOOLS!=yes.  This permits objdirs to
  be created even when USETOOLS=no.

* Clean up use of "-m" by specifying it to .MAKEFLAGS: if needed.

Work around parallelism lossage, because .ORDER doesn't work yet
(noted in PR bin/14404).  This will be fixed back to using .ORDER later.

Add rules for generating plaintext and HTML versions of the "BUILDING"
document automatically (to be checked in when BUILDING.mdoc is changed).

Re-add intermediate dependall/install targets (do-lib-csu, do-lib,
do-gnu-lib) to permit restarting broken builds in the middle.

Add shortcut rules to avoid going into distrib on unneeded (and in some
cases, currently broken) targets.

Revert previous.  etc and distrib do now belong in _SUBDIR; the correct fix
for broken builds is to fix the relevant Makefiles as was done for sparc.
This was done in the interest of simplicity of the system build (and the
fact that there may be a need to descend into these directories in the
near future).

Remove distrib and etc from _SUBDIR. These should never get added to the
subdir list as anything building into them will access them directly (ala
the make release rule or the mtree rule). There were good reasons for
controlling this at the top level before and those should remain in place.

On cleandir and obj builds these should get run through but that's it for
the "normal" rule sets. (This was breaking the builds as make includes doesn't
function inside of distrib for instance).

Add a couple more shortcut rules for the "tools" subdir to prevent recursion.

Change
  ${USETOOLS} != "no"
to
  ${USETOOLS} == "yes"
to allow USETOOLS to be tri-state:  "yes", "no", or "never".  The use of
these options will be documented in src/BUILDING.

Overhaul and simplify the top level Makefile, and add some sanity checking.

- "make build" cannot be invoked from the command line at the same time as
  any standard recursive target except "obj" and "cleandir", as things like
  "make all release" can lead to unexpected results.

- Put everything in SUBDIR, and auto-weed missing directories.  This allows
  the standard targets to work as expected (including in tools, etc, and
  distrib).

- Leverage .for loops to simplify the prerequisite dependall/install phase
  of compile-time dependencies (lib/csu, lib, gnu/lib).  These are now all
  distilled into one component rule ("do-build").

- Use the actual targets of obj, cleandir, and includes; no need for double
  indirection goop in this case.

- GC all the deprecated "domestic" cruft.  We are officially using (and
  fixing, where appropriate) the cryptosystem integrated into src/crypto.

- Collapse the whatis.db build rule into a dependency of "afterinstall",
  and nuke the "_BUILD" cruft.

Use @true instead of @${TRUE} in includes-foo targets, since there is no
variable TRUE defined in our makefile system.

This prevents "make includes" from breaking with older bsd.subdir.mk, and is
more consistent with the uses of "true" in the rest of the tree.

Do not descend into `tools' on make clean{dir,} if USETOOLS=no, as doing
so without TOOLDIR set will blow up.

Add "tools" to the list of subdirs for an explicit "make obj" or
"make cleandir".  Fixes PR bin/14177.

"make build"'s logic and the conventional <bsd.subdir.mk> logic probably
need to be split apart here at some point to prevent these kinds of things
from causing odd problems in the future....

Use ${.CURDIR}/share/mk to include bsd.own.mk and bsd.subdir.mk into this
file in order to get proper definitions for a build.  (Temporary; this
Makefile will be moved to a new name and replaced with a bootstrap Makefile
in the near future.)

UPDATING (1.38) says:

        i386 platform builds must now set TOOLDIR in mk.conf or the
        environment in order to build the system.  This is a pathname
        where host build tools will be installed, and must NOT be
        the same as src/tools.

        (Optionally, USETOOLS=no can be set in the environment if you
        wish to avoid using the separate host toolchain for building a
        subtree.  Otherwise, this will default to "yes" automatically.)

However, building with USETOOLS=no set and no defined TOOLDIR ends up
with breakage, as the do-make-tools target is run regardless of whether
or not USETOOLS is set.

Hence, a wrapper around the body of the do-make-tools target:

.if ${USETOOLS} != "no"
...
.endif

...which makes the build work when USETOOLS=no, with no TOOLDIR set. This
would seem to more accurately match the description put forth in UPDATING.

Put do-make-tools before creating distrib-dirs (as binstall has to be
available before making distrib-dirs).

Always use src/share/mk as the source of the system .mk files for a build.

- Remove the include of Makefile.tools; this will be done elsewhere.
- Skip the "includes" phase of bin, games, libexec, regress, sbin, and usr.sbin.

Make sure DESTDIR is always set when calling the distrib-dirs target.
In the new build world order, DESTDIR is set to "" (in Makefile.tools)
if not already set, to ensure correct include/library handling.  This
caused the top-level to not set DESTDIR=/, which confused distrib-dirs,
since it doesn't include Makefile.tools, and thus didn't see the same
DESTDIR that the top-level did.

The final step -- hook src/tools into the main build.  If USE_NEW_TOOLCHAIN is
set, will descend into "tools" to build a toolchain, and use that toolchain
explicitly for the build (via tools/Makefile.tools).

While here, GC all the "egcs-detection" logic; it's not needed anymore, since
nothing is on gcc 2.7 any longer.

Wrap a long line.

Document the cool NOCLEANDIR/NOINCLUDES options that somebody added.

Sync w/ netbsd-1-5-base.

Merge a bunch of things from crypto-us and crypto-intl into basesrc,
adding support for Heimdal/KTH Kerberos where easy to do so.  Eliminate
bsd.crypto.mk.

There is still a bunch more work to do, but crypto is now more-or-less
fully merged into the base NetBSD distribution.

remove two of the previous ${_M}; they were invoked before $DESTDIR/share/mk may have existed.  add one more.

Add ${_M} where it was missing in a few places.

HAVE_GCC28 -> HAVE_EGCS, and make it match gcc 2.9, as well.

if MAKEOBJDIRPREFIX defined, include etc in make obj

use MKSHARE=no instead.

fix long standing bug in `make build' with $DESTDIR:
- during `make build' after /usr/share/mk has been installed, call
  make with `-m $DESTDIR/usr/share/mk'.

At least one crypto-intl lib has an info file(s) - add MKINFO=no to the
early build of ../src/lib ala ../src/gnu/lib.

Handle new make variable BUILD_DONE which creates an empty build target if
it is set.

When you type `make obj', make obj dirs in distrib whether or not you
have MKOBJDIRS variable set.

Add a buildmsg target for build to depend upon instead of using an ifmake block.  "make snapshot" now echos the start of build time.

share/tmac is now installed by `make includes', so don't do it again.

Make 'make build' hook into crypto-tree for crypto specific build-time
dependencies.

make sure include and include/sys are populated before starting to
make includes in lib

Pull up to last week's -current.

After ${MAKE} obj, explicitly make obj dirs in ${.CURDIR}/distrib as well.

Revert previous but move "cd share/tmac" later down so that any
generated files will go in obj dirs if they are created.  After
discussion with the two Bill's on tech-userlevel.

Move the "${MAKE} obj" above the share/tmac stage so that the generated
files in that directory don't pollute the source tree before the obj
dirs are created.

Document MKOBJDIRS here, and sort the variable list in the comments
into alphabetical order.

Add MKOBJDIRS make variable to bsd.own.mk, defaulting to "no" but
overrideable in mk.conf

Document in bsd.README; this is distinct from "MKOBJ", which controls
whether "make obj" does anything.

In the top-level makefile, if MKOBJDIRS != "no", do a "make obj" at an
appropriate point during a "make build".

use new dependall target instead of depend then all in make build

Remove all of the domestic/crypto-us glue from this file.  It is handled
differently now.

Handle crypto-us just like domestic

Add the FORCE_DOMESTIC flag to force the 'all', 'includes',
and 'install' targets to descend into the domestic subtree.  This is
generally a bad idea unless one knows precisely what they're doing,
but we'll provide the rope anyway (with the appropriate warnings).

Document both EXPORTABLE_SYSTEM and FORCE_DOMESTIC at the top of the file.

Improve documentation.

Make a note of a subtle lossage mode pointed out by Mycroft.

Make the includes and install targets consistent, and shove the
ugly hack into the etc/Makefile distribution target instead of
the top-level build target.  Problem noted by Mycroft.

Back out rev 1.90:  The need for texinfo is a one-shot event.  This was
announced in a reasonable forum.  Further, it adds significant overhead to
the build process, and doesn't work correctly when a non-root DESTDIR
build is attempted (unless texinfo is already available, which of course
makes this change unnecessary).

make -> ${MAKE}

Build and install texinfo before building and installing the world.

Don't try to run makeinfo when doing preliminary GNU library builds.

Revert 1.83; it doesn't work.  A different fix for his problem is in
the pipeline.

Add release and snapshot targets. (They do the same thing.)

convert from NOxxx= to MKxxx=no.
include <bsd.own.mk> if testing a MKxxx variable.

Back out the info dir changes; /usr/share/info was not in pkgsrc's info
path, which confused me to no end.

If updating from a system which has a /usr/pkg/info/dir, move that to
/usr/share/info/dir and make a symlink in /usr/pkg/info.  This allows
systems with the gtexinfo pkg installed to work "properly".

Build the domestic libraries first, before building programs. Unfortunately
some programs like /usr/libexec/ftpd, need the kerberos etc libraries.
XXX: In reality programs like these should be moved to the domestic tree!
I would have assumed that if I make install in the exportable tree, I will
not install any domestic binaries!!!

Once more, from the beginning:  we really, really don't want to descend into
the domestic tree if we are building an EXPORTABLE_SYSTEM.

Translate the conditional to English so as to avoid future problems
when people are tempted to modify it.

If doing a "domestic" build, make sure whatis.db is built _after_ the
domestic tree.

Sigh.  The last change was too clever.  Instead of using EXPORTABLE_SYSTEM,
which has side effects, use _BUILD to determine whether we ought to
install things in the domestic subtree.  Otherwise, the core idea from
the last revision is unchanged.

When I split the build target into the top-level and "domestic" pieces, I
failed to account for how a 'make distribution' would get the proper bits
into the distribution tree.  To correct this, we set EXPORTABLE_SYSTEM
while doing a 'make build' in order to avoid trying to install not-yet-
generated headers and binaries.  I've also made the required adjustment
to the condition that adds "domestic" to SUBDIR.

This is too hairy and needs to die, but I don't see how it can until
we integrate the crypto bits into the main body of the tree.

Don't build domestic bits directly; use the domestic 'build' target
to do them for us.

Even if EXPORTABLE_SYSTEM is defined, descend into domestic for targets
obj, clean, cleandir and distclean. This reduces the chance of problems
(and the need to re-run make obj) if one is switching back and forth
between EXPORTABLE_SYSTEM and not, as US/Canadian developers tend to do.

Add a 'NBUILDJOBS' variable which control the number of jobs started in
parallel for a 'make build' (using make's -j flag). Only CPU-intensive jobs
are started in parallel.
Document the variables useable at the begining of the makefile
(NBUILDJOBS NOMAN NOSHARE UPDATE DESTDIR). Feel free to add documentation
for the ones I forgot !

GC old gcc 2.7.2.2.

Let make do the NOMAN= variable assignments instead of the shell so us
csh/tcsh weenies can cut and paste "make -n build" lines.

It is no longer necessary to run ldconfig in the build: target.  It is
handled by bsd.lib.mk.

Only ldconfig if it's there (ELF systems don't use ldconfig).

Do not build libgcc 3 times.
Instead:
* If upgrading the compiler, build it *first*, before anything else.
* If upgrading the compiler and DESTDIR is set, barf.
This guarantees that libgcc is built during the library stage.

When doing a `make build' without DESTDIR, run ldconfig(8) after updating the
libraries.

Fix libgcc on alpha; shouldn't build 2.7 libgcc when bootstrapping.

don't install in /usr/share if NOSHARE is defined

Test gcc2.8 and egcs properly

No need to shield alpha from gcc 2.7 libgcc any longer.  Default is egcs.

Only build the egcs libgcc if the current ${CXX} is actually egcs.

Re-enable libgcc from egcs and RE-ADD the warning & libgcc rebuild at the
end of the build - it is needed for gcc 2.7->egcs bootstraps!

Turn off the egcs bits while the 1.1 import is taking place.

Don't try and build non-EGCS libgcc on Alpha and PowerPC.

During the initial library pass, do not install man pages.
Also, GC the weird egcs stuff in here.

Do not blow away my egcs libgcc at the beginning of a build.

Fix flawed logic: I'm not all here today.  (.if's werten't doing what the
commit comment said they would do.

Fix the rebuild of libgcc:
- If USE_EGCS is set, rebuild egcs's libgcc and install it
  (unless DESTDIR is set and system compiler is not gcc 2.8,
   in which case print a warning message and do nothing).
- Do not rebuild gcc 2.7's libgcc.  egcs can build this fine.

build libgcc during make build; also, don't build lex and yacc first any more.

Revert 1.44 and associated changes; you can't prebuild anything without
includes, which is the case if you are building to an empty $DESTDIR.
Fixes PR 5497.

NOTE:  This reverts us to the 1.3 behavior of requiring the secr
set to be installed for non-exportable builds.  While unfortunate,
this allows a user to start with existing binary sets, rather than
requiring special knowledge of how to build a domestic tree to
$DESTDIR.

Move (re)build of libgcc to end of build list (after gcc/egcs would be
installed/updated).

Gack, don't try to build libgcc if it wouldn't be appropriate.

Build the appropriate libgcc, so that build-to-destdir works.

Make sure system includes are installed before descending into gnu.

Do the cleandir before the includes, so rpcgen doesn't build includes
twice.  (Should build and install rpcgen before the includes, but it's not
too clear whether to do this before or after the cleandir.)

Pull up 1.45-1.50: make build fails!

Print date after build completes as well as before.   Previous code failed because make build depends on beforeinstall but not afterinstall.

fix make build for non-usa domestic a better way

don't assume domestic/usr.bin/compile_et exists for make build (eg: the user has a non-USA domestic subtree)

In the build targer, make sure the troff macros are installed before
attempting to build manual pages.

Domestic library build fix: libtelnet depends on libdes and libkrb.  libkrb
depends on libcom_err.  So, build libdes, libcom_err, libkrb in that
order before building domestic/lib.  (Geez, this stuff is a mess.)

Pull up 1.44 (mellon) and 1.45 (perry)

add date printout at beginning and end of 'make build's

Prebuild some things that the build depends on *before* they are needed so that fresh builds don't die prematurely

Pull up from trunk:

Make the "build" target depend on "beforeinstall", ensuring that all
directories have been created for the installation of the include files.

Make the "build" target depend on "beforeinstall", ensuring that all
directories have been created for the installation of the include files.

Back out BUILDDIR and NOINSTALL changes.

Add a cleandir to make build, to make it more like it was before.

These updates to the build allow building against include files
and libs in the object tree, if you use a separate object tree,
while maintaining backward compatability with other build methods.
See the notes in src/share/mk/bsd.README for full details. Note
that the `make includes' target now only installs the include files
in the build directory (if you use one--otherwise they go in DESTDIR
just like before); `make install' will install include files in
DESTDIR.

Don't cleandir on make build when UPDATE is set.

when doing 'make build', build lib/csu & install it before building
lib itself.  On the Alpha (and other ELF systems), shared library builds
require files built/installed by the csu build, so if lib/csu isn't
built/installed before lib is, DESTDIR builds won't work and normal builds
can mistakenly use old versions of some csu files.

All of domestic/lib now builds without errors, so we build it all.

allow builds to work if directory games is missing. Closes pr misc/1921 and
misc/2294

Headers in src/domestic/include are now installed by the includes target

Headers in src/include are now installed by the includes target

Added "${MAKE} includes" to build target

pull in bsd.own.mk earlier, to get configuration variables.
if people define EXPORTABLE_SYSTEM, they REALLY don't want to do stuff
	in 'domestic'.  Pay attention to it when doing 'make build'.
in 'make build', install share/mk _first_, because include dirs may
	require new make templates.
in 'make build', install domestic includes after normal includes, so
	they can previously-installed includes if necessary.
Note that all of domestic/lib should be built in 'make build' during the
	library build stage.

behaviour of 'make build' should not change if DESTDIR is set; this is an artifact of an ancient mistake of mine.

a futile nod to ease-of-upgrade: make build now installs new rules from share/mk.

removed obsolete src/kerberosIV reference, albeit commented out

fix typo

libcrypt has moved

get krb4 includes installed, do distrib-dirs if DESTDIR not set

New-style RCS id.

Comment out last change as it interferes with distribution building.

stick distrib-dirs in beforeinstall -- should be cleaner?

work in the face of a /usr/src/obj directory

add 'domestic' to subdirs list, if it exists.

explicitly pull in bsd.own.mk, so that it's there for afterinstall.

if not installing man pages, don't remake whatis db

light style cleanup

don't use 'make' explicitly

kill typo

add some new targets to DTRT when installing/building

do "lib" first.  otherwise you can be *really* screwed by a 'make install'
on a system with shared libraries...

Make regress only if directory exists. It can be optional.

allow toplevel makefile to descend into sys

change from rcs "Header" to "Id"

oops, clean that up a bit

add regress, but not for install.  also, add "regress" target

put all of the gnu stuff in one place

added gnulibexec gnugames

added `usr.gnubin' for new gnu binaries necessary for the distribution.

added gnulib, for gnu libraries that for whatever reason need to go
into the main tree

change "Id" to "Header" in rcsid, and noted why etc was not in subdirs

added rcs id

after 0.2.2 "stable" patches applied

initial import of 386bsd-0.1 sources
