boot1.o: In function `fsread_size':
/usr/src/sys/boot/powerpc/boot1.chrp/boot1.c:(.text+0x14b8): undefined
reference to `__udivdi3'
/usr/src/sys/boot/powerpc/boot1.chrp/boot1.c:(.text+0x1508): undefined
reference to `__udivdi3'
cc: error: linker command failed with exit code 1 (use -v to see invocation)

is from the buildworld part of the overall build
attempt.

I'll note that back in -r317820 and before I was
able to buildworld and installworld based on the
system clang and use the installed world on an
old PowerMac (other than handling thrown C++
exceptions).


Also: trying buildkernel separately after the
buildworld failure worked fine. [That does not
mean that such a clang-based kernel would
complete the boot sequence on an old PowerMac.]
