I'll note that for powerpc64, and the historical range of
devel/powerpc64-gcc vintages that I've tried over the years,
I've never had a WITH_LIB32= buildworld end up with a lib32
environment that worked. crtbeginS seems to get some code
generation (register usage) from the wrong ABI and ends up
using R30's value as a bad-address to dereference
inappropriately. WITHOUT_LIB32= may be appropriate.

(lib32 works in my experimental clang-based buildworlds.
But clang has other problems for powerpc64 and 32-bit
powerpc.)
