Add the move-aout-libs upgrade target so that people who have already
gone elf can put their libraries through the mincer. Anyone who hasn't
deleted aout libraries from /usr/lib (but has done a make world putting
the new aout libs in /usr/lib/aout) will be asked for confirmation
to delete them one by one.
- Moved most of the guts of Makefile to Makefile.inc1 to become the
backend for the build system.
- The new Makefile doesn't suffer from problems including the wrong
sys.mk because it doesn't use anything in there or bsd.own.mk. So,
from now on, the proper build command is just `make world' (or
buildworld).
- The intermediate makefiles called Makefile.inc0 and Makefile.upgrade
fiddle with the OBJFORMAT and MAKEOBJDIRPREFIX variables so that
both aout and elf object trees can coexist. Makefile.upgrade contains
the aout->elf transition build.
- A cross build environment is now very close to reality. Specifying
TOOLDIR, setting OBJFORMAT and MAKEOBJDIRPREFIX allow that.

for building and installing a local sendmail.cf..
I'm a little nervous about the implications of having an obj dir built
under etc (to get to the obj dir for sendmail), but the make rules appear
to DTRT.
recently added definitions from sys.mk to bsd.own.mk. Include the
src-relative bsd.own.mk in src/Makefile to pick up all new definitions.
Don't check that MACHINE_ARCH is defined in src/Makefile, since it is
(and should have been) guaranteed to be defined.
working when the target system is not binary compatible. Use various
hacks to work around minor problems in the source and binary tree
layouts:
- caesar and strfile are built normally (the source layout is good),
then installed by copying them to ${WORLDTMP}/usr/bin (they are
installed in ${WORLDTMP}/usr/games, but I don't want to put that
in $PATH).
- colldef and mklocale are built and installed normally. Messy and
incomplete relative path searches for them and caesar and strfile
can now go away.
- internal tools that aren't installed are now built and left lying
around for the `make all' pass to use. If the target system is
not binary compatible, it is critical that these tools don't get
rebuilt. Cleaning of the obj tree before building the internal
tools should ensure this.
- most internal tools are built using internal build-tools targets,
but tn3270 is simpler for a change - it has all the tools in a
separate tree, so they can be built using `make all'.
build at least compile_et and lex, and although almost any version
of yacc could work, the version in -stable doesn't actually work
with -current makefiles because it doesn't support -o.

- don't announce `mtree' as `mtools'.
- don't install to ${DESTDIR}/usr/sbin (which often doesn't exist if
DESTDIR is set and may be read-only if DESTDIR is not set).
- install to (${WORLDTMP}/usr/sbin so that the new mtree is actually
in $PATH if DESTDIR is set.
- don't use the host make or the host sys.mk. This is probably
unimportant.
- use a temporary obj dir like the one for `make'. This was mainly
necessary because I forgot to remove the MAKEOBJDIRPREFIX unsetting
which was just a bug for mtree. A non-quick fix would handle mtree
more like a bootstrap tool (the only additional complications are to
create ${BINDIR} and avoid excessive cleaning). Except a non-quick
fix would change much more.
(in particular, if DESTDIR is empty or "/"), then the host's ldconfig will
be the target's ldconfig by the time it is run.
Fixed disordering of env.
Don't know too much about libcrypt. Use exactly the same definition of
_libcrypt as lib/Makefile.
Don't build strip twice.
commit - don't wander off to bootstrap mtree and include in the middle
of bootstrapping lex, and don't forget what we were doing and build
some lex obj dirs twice.
crypt library should be used when building bootstrap-libraries. This
make it work on machines that don't have the secure directory.
Thanks to Paul Allenby <pallenby@mikom.csir.co.za> for bringing it to
my attention.
for the rest of the build. I'm not certain, but I think this determines
which crypt() goes into /sbin/init. This change shouldn't hurt anyway. :-)
Based on a suggestion by: bde
real source tree, the bootstrap target would attempt have cpio copy the
files over themselves, unlinking them first. I think this only happened
with make -DNOCLEAN world at the transition between a symlinked
objdir/tmp/usr/include/{sys,net,..} and real files.
with real copies. I'm sick of !@#&!^!@#*& mtree chowning directories in
my src/sys/* tree after it follows the symlinks. I still believe that
mtree is broken for doing this (introduced in mtree.c rev 1.5).
helpful to stop it running /usr/libexec/aout/as for real while bootstrapping.
Only force a strict path when we really have built all the tools in
$OBJDIR/tmp/usr/libexec/*.
Move a.out libraries to /usr/lib/aout to make space for ELF libs.
Make rtld usr /usr/lib/aout as default library path.
Make ldconfig reject /usr/lib as an a.out library path.
Fix various Makefiles for LIBDIR!=/usr/lib breakage.
This will after a make world & reboot give a system that no
longer uses /usr/lib/*, infact one could remove all the old
libraries there, they are not used anymore.
We are getting close to an ELF make world, but I'll let this
all settle for a week or two...
Move our old a.out utils to /usr/libexec/aout.
Enable binutils and put the utils in /usr/libexec/elf
Enable objformat, a little helper program that calls the right
utils based on /etc/objformat and $OBJFORMAT.
This will enable the ELF generating tools.
Remember that this is only step one, the system is still compiled
and run in a.out format ONLY.
Problem left to solve: The BSD manpages wins over the GNU equivalents
as the are installed last. We need to distinguish between the manpages
somehow...
execution is usually unnecessary in BSD Makefiles because BSD make
invokes shells with -e. Using it to give conditional execution is
often wrong in BSD makefiles because BSD make joins shell commands
when invoked in certain ways (in particular, as `make -jN'). Example
makefile:
---
clean:
cd /
false && true
rm -rf * # a dangerous command
---
This should terminate after the `false && true' command fails, but
it doesn't when the commands are joined (`false && true' is a non-
simple command, so -e doesn't cause termination). The b-maked version:
---
clean:
cd /
false; true
rm -rf * # a dangerous command
---
terminates after the `false' command fails (`false' is a simple
command, so -e causes termination). However, for versions of
make like gnu make that don't invoke shells with -e, this change
completely breaks the makefile.
This is one of the fixes for the bug suite that caused `make world'
to sometimes put raw cpp output in .depend files. Building of cc
sometimes failed, but the failure did not terminate the build
immediately, and various wrong versions of the cc components were
used until one was wrong enough to cause a fatal error.
The headers that are installed in WORLDTMP are part of the interface
that includes libraries like libc, so they must be installed together.
This means that lib-tools and build-tools should be merged. The FreeBSD
build only works in hosted form where it is assumed that the installed
version contains adequate tools to build the latest release.
`make world' by about 14% here (down to 4490 seconds real on a
K6/233). Temporarily skip this optimization when building with
-j, since there are still many broken makefiles.
Fixed NOCLEANDIR option. Cleaning of `.depend' was broken.
Put -nostdinc in CFLAGS, not in CC, and don't override the default
CC. This fixes enforcing use of ${WORLDTMP}/usr/include.
Don't install library man pages in ${WORLDTMP}.
`make world' times by about 10%. Use a new `bootstrap-libraries'
target to build just enough (static) libraries to bootstrap the
tools, and delay building of shared libraries until all the tools
have been built.
Fixed `/usr/bin/make world'. The version of `make' that we buildis
nand use is named "make", not ${MAKE}.
cleaning doesn't affect the normal copy. Save a little time by not doing
unnecessary clean, depend nd cleandepend steps.

Added xargs to build-tools. It may be used for kdump and truss.
