--- Comment #2 from Mark Millard <markmi at dsl-only.net> ---
Nathon Whitehorn had me instead test building based on
sys/boot/powerpc/kboot/Makefile having 2 powerpc64 specific options removed:
# svnlite diff sys/boot/powerpc/kboot/Makefile

The TARGET_ARCH=powerpc build completed with the following messages (from
grep'ing for kboot in the typescript file):

The compiler involved was clang 3.8.0 . (This was a WITH_META_MODE=yes build.)
The TARGET_ARCH=powerpc64 build also completed. The compiler involved was
powerpc64-gcc. (This was a WITH_META_MODE=yes build.) It showed the warnings:

I also did gcc 4.2.1 based cross-builds for TARGET_ARCH=powerpc and
TARGET_ARCH=powerpc64 and they completed. They had analogous warnings to what
clang (powerpc) and powerpc64-gcc (powerpc64) produced.
I do not have a context to test powerpc64 or powerpc kboot in. But the above
shows that the TARGET_ARCH=powerpc will build if the file is adjusted.
