remove the xfree86 reachover makefiles and the vast majority of
the support in the rest of the source tree.

X11 sets could use some cleaning up perhaps (just deletion, as
we've never really marked the old X11R6 as obsolete for native
xorg using platforms so far either.)

Add MKCOMPATX11 knob for making X11 compat libraries.

Support building the xorg X11 libraries under MKCOMPAT.
Add XORG_MACHINE_ARCH to compat's bsd.*.mk
Turn xorg makekeys and makestrs into real host tools which are installed into
${TOOLSDIR}

Add tests/share/mk and external/bsd/atf/tests/atf for MKCOMPATTESTS

Add support for MKCOMPATTESTS

Implement build_install in src/lib/Makefile, which traverses the
subdirectories and invokes dependall/install. Do this in groups
delimited by .WAIT to ensure that depending libraries can use the
installed versions and don't need to know the locations in the source
tree.

Use this new target in src/Makefile to replace most of the adhoc library
logic with two special cases, src/lib and src/compat. Adjust
sys/Makefile to include the module directory when building them. Add
some necessary .WAITs in src/lib/Makefile to reflect the dependencies
from src/Makefile and also add the rump libraries here.

branches: 1.7.4;
if using MAKEOBJDIRPREFIX, make sure to unset it since it would override
the use of MAKEOBJDIR.

Change to use MAKEOBJDIR instead of MAKEOBJDIRPREFIX

branches: 1.5.2; 1.5.4;
Remove the do-external-lib and do-gnu-lib targets, along with
external/lib/Makefile and crypto/external/lib/Makefile, replacing
them all with SUBDIRs directly from lib/Makefile.

compat/compatsubdirs.mk becomes simpler now, as everything is built
from lib/Makefile, meaning all the libraries will now be built under
compat so update the set lists to account for that.

Hook up xz into the build system.

add iscsi/lib

don't build atf, openldap or binutils if their MK* == "no".

- move the per-platform subdir list into archdirs.mk
- move the per-ABI subdir list into compatsubdir.mk. use the new
MAKEDIRTARGETENV support to force a new objdir for compat library builds,
and simply traverse over the normal src path once for each ABI to be
built. this eliminates all the shadow Makefile's for every library, and
allows multiple compat ABIs to be built for a single platform, such as
both o32 and n64 for mips64's default n32.
- compat/Makefile is merely a subdir provider now, and takes the real
information from archdirs.mk

Clean up for ticket #1499 - doubled content, not sure how it happened.

Apply patch (requested by mrg in ticket #1499):

src/compat version 2. this allows building any number of alternate
library / program target ABIs. rather than duplicating the list of
subdirs and Makefiles to build, it re-traverses the necessary ones.
details:
- add support for MAKEDIRTARGETENV to share/mk
- renames LD32DIR to MLIBDIR
- fixes library builds for some subdirs (more was built than needed)
- fixes /bin & /sbin apps in compat mode
- reduces complexity in src/compat and the rest of the tree
- updates ldd netbsd32 support

file compatsubdir.mk was added on branch netbsd-5 on 2011-01-06 05:19:55 +0000
