looking at the diff in external/gpl3/gcc/dist/gcc/config/rs6000,
i see that we have a lot changes vs eg, vs gcc-8-3-0 import or
the pkgsrc gcc 8 (which has zero rs6000/powerpc changes).
they're for ppc64, but also several other ones.
we also have patched config.gcc heavily for rs6000 and maybe
things i would start with:
- revert rs6000.c changes
- revert config.gcc powerpc changes, and perhaps also the bit
- try to figure out how to revert type-definitions changes
but nothing looks obvious to me.
