I hereby withdraw this patch, it was based on a misunderstanding.

Alexandre Oliva, happy hackerhttps:
The rs6000.md copysign3 expander requires the mode to satisfy
FLOAT128_IEEE_P, so requiring float128 on ppc for ifn_copysign
effective target is hopefully a close-enough approximation.
gcc.dg/fold-copysign-1.c and gcc.dg/pr55152-2.c fail on ppc-elf
without this.
