This was in a poudriere bulk build on a head -r347549 based powerpc64
system with system clang 8 for cc and c++ and base/binutils
for ld. I was attempting a build with the -O1 changes disabled. (Note:
the system is self hosting for buildworld buildkernel via the clang 8
and base/binutils combination.)
So having issues with building lang/gcc8 is not limited to gcc 4.2.1's
tool chain for powerpc64. (I've not yet tested -O1 use as the bulk build
still has lots of other things to build.)
