arm64 relies on an external binutils port or package right now, because
the in-tree linker from binutils 2.17.50 does not support arm64. Add
arm64 to universe if the linker is available. If not output a message

buildworld and buildkernel use the external binutils automatically, so
it's sufficient to run 'pkg install aarch64-binutils' to build

During "make buildworld", building bmake is (one of) the very first steps
and we should not be building any of its tests. Conceptually, this is the
right thing to do 1) for build simplicity reasons and 2) because there is
no need to build any tests this early on.
In practice, this fixes tinderbox builds of CURRENT from 9.x when MK_TESTS
is enabled. This is because bsd.test.mk needs some modern bmake features
not present in 9.x (:tW) and tinderbox is forcing the build to use the
CURRENT share/mk files from the very beginning (see r266617). By skipping
the build of the tests when still using the host make, we omit the problem.
Arguably, what tinderbox is doing is wrong and needs to be addressed, but
that is a separate issue.

starting the kernels. Before this the kernels would be built as part of the
last architecture universe target. There can cause problems when this world
finishes before the other worlds as the host compiler may be picked up
rather than the target compiler.
The solution is to add a target to build the universe kernels that depends
on all the world targets finishing. As we may not be building a world only
depend on it when MAKE_JUST_KERNELS is undefined.
The automation can set TARGET_ARCH and TARGET and then make various
top-level targets, including buildLINT and buildkernel (with
KERNCONF=LINT). Previously there was no way to generate the LINT
kernel configuration without having to do something exceptionally
painful.
1. Don't do upgrade_checks when using bmake. As long as we have WITH_BMAKE,
there's a bootstrap complication in ths respect. Avoid it. Make the
necessary changes to have upgrade_checks work wth bmake anyway.
2. Remove the use of -E. It's not needed in our build because we use ?= for
the respective variables, which means that we'll take the environment
value (if any) anyway.
3. Properly declare phony targets as phony as bmake is a lot smarter (and
thus agressive) about build avoidance.
4. Make sure CLEANFILES is complete and use it on .NOPATH. bmake is a lot
smarter about build avoidance and should not find files we generate in
the source tree. We should not have files in the repository we want to
generate, but this is an easier way to cross this hurdle.
5. Have behavior under bmake the same as it is under make with respect to
halting when sub-commands fail. Add "set -e" to compound commands so
that bmake is informed when sub-commands fail.
6. Make sure crunchgen uses the same make as the rest of the build. This
is important when the make utility isn't called make (but bmake for
example).
7. While here, add support for using MAKEOBJDIR to set the object tree

testing for variables that are always defined (e.g.,
"make -V CC") would still print a false warning. Fix
this by only passing a submake the MAKEOBJDIRPREFIX=*

"MAKEOBJDIRPREFIX = foo" (with embedded spaces), but
these are unorthodox enough to not care about them.
The make(1) bug mentioned in the previous revision
was just fixed in make/main.c,v 1.109.
When make flags are passed to make in the environment, the string is
chopped up in an (argc,argv) vector. This happens in brk_string() and
the chopped up string is stored in static buffer. When this includes
something like "-V BINMAKE", then a pointer into the static buffer is
put on the variables list for evaluation later. However, brk_string()
is used for more than just chopping up the MAKEFLAGS env. variable, so
it's very likely that the static buffer is clobbered. In fact, this is
exactly what happens.
The result is that _MAKEOBJDIRPREFIX gets assigned whatever garbage
the child make happens to emit, causing the test to fail. Like this:
pluto2% cd /usr/src
pluto2% make -V BINMAKE
"/q/6.x/src/Makefile", line 94: MAKEOBJDIRPREFIX can only be set in environment, not as a global (in /etc/make.conf) or command-line variable.
pluto2% make -dv -V BINMAKE | & grep _MAKEOBJDIRPREFIX
Global:_MAKEOBJDIRPREFIX = }
The fix is to not use MAKEFLAGS for this, but simple pass the flags
as arguments. Ideally make(1) should be fixed but that's beyond the
scope of my attention span.

To overcome this problem, we now take the following approach:

- We check to see if ${MAKE} passes the regression tests.
- If it does, we use it. Otherwise, we build and use an

make in /usr/bin. This is both bogus and does not work under non
root. So, rather than overwriting the existing /usr/bin/make, we
now install it into a safe location, and use it from there.

Errors from the individual steps are ignored and the stdout+stderr
are saved in distinct files in root of the source tree with names
like: _.${arch}.${target}
On my dual 1.6G Athlon it takes roughly four hours to run this target.
under way to move the remnants of the a.out toolchain to ports. As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL. It has already lasted WAY beyond
that.
Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.
Tested on: i386 (extensively), alpha
which fails the make tests (doesn't understand ${notdef:U}) and therefore
fails on __FBSDID in usr.bin/make/*. -DBOOTSTRAPPING is no help here since
this is before we are using the new share/mk/* files, and it would conflict
with the builtin -DBOOTSTRAPPING support later.. so use a different flag.
