>Description:

I seem to be having some build issues happening.  My pertinent environment/variables are as follows:

MACHINE=<amd64>
MACHINE_ARCH=<(not set)>
MAKEOBJDIR=</usr/src/build/arch/amd64/obj>
DESTDIR=</usr/src/build/arch/amd64/build/>
RELEASEDIR=</usr/src/build/arch/amd64/release/>
PATH=</usr/src/tools/tools-amd64/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin:/usr/X11/bin:/usr/X11/sbin:/root/bin:/root/bashmodules>
MANPATH=</usr/src/tools/tools-amd64/man:>
BSDSRCDIR=</usr/src>
BSDOBJDIR=</usr/src/build/arch/amd64/obj>
BUILDROOT=</usr/src/build>
TOOLDIR=</usr/src/tools/tools-amd64>

MACHINE_ARCH is not set because things seem to go horribly wrong when it is set to x86_64, even though that appears to be the default MACHINE_ARCH for MACHINE=amd64.

My command line (general) is as such:

./build.sh -m amd64 -D /usr/src/build/arch/amd64/build/ \
	-O /usr/src/build/arch/amd64/obj \
	-R /usr/src/build/arch/amd64/release/ \
	-T /usr/src/tools/tools-amd64 -j12 {target}

Doesn't matter what my target is -- that command line works just fine; UNLESS:

If I add '-u' t o that command line, I get failures.  Isn't -u supposed to
skip cleandir and the tools rebuild?  The tools rebuild fails if the tools
already exist.  (This bug has been present for quite some time.)

If I add '-x' (to build X11), I get failures before the toolchain finishes
building.  Why there?  Does the toolchain contain any weird X11 dependencies?

So right now, I can't do a build-by-stages (tools, build, distribution,
release).  I can only pick one target and build to that, as each build
seems to require a total wipeout and restart.

My /etc/mk.conf:  https://www.starwolf.com/machines/eddie/mk.conf

Build Logs:
"build release", success: https://www.starwolf.com/machines/eddie/buildlogs/2019-09-23/1433-build-release.out.gz
"build release with -x", failure: https://www.starwolf.com/machines/eddie/buildlogs/2019-09-24/0031-build-release-fail.gz

"build tools", success: https://www.starwolf.com/machines/eddie/buildlogs/2019-09-24/0105-build-tools.out.gz
"build tools with -x", failure:  https://www.starwolf.com/machines/eddie/buildlogs/2019-09-24/0228-build-tools.fail.gz

I do in fact have the X sources at /usr/xsrc, updated 2019-09-23 (and
nothing new seems to have come in).

>How-To-Repeat:
	./build.sh -m amd64 -D /usr/src/build/arch/amd64/build/ \
	-O /usr/src/build/arch/amd64/obj -R \
	/usr/src/build/arch/amd64/release/ -T /usr/src/tools/tools-amd64 \
	-j12 -x {tools|build|release}

	Not known at this point.
