I do not have access to powerpc's currently so I'm just going to be doing
cross-build tests for TARGET_ARCH=powerpc and TARGET_ARCH=powerpc64 (from
amd64) based on the below updates.
You initially mention "two flags" but then only explicitly request removal of
one (the -CFLAGS+= -Wa,-mppc64bridge line).
I'm assuming that the -mcpu=powerpc64 is also to be removed if powerpc (non-64)
is to be covered. See my intended test below. Let me know if it is not what you
want.

(I.e., I reverted sys/boot/powerpc/Makefile.)
