* sysdeps/powerpc/powerpc32/__longjmp-common.S (LOAD_GP): Define
macro conditional on [__SPE__ || (__NO_FPRS__ && !_SOFT_FLOAT)].
(__longjmp): Use LOAD_GP to load saved GPRs.
* sysdeps/powerpc/powerpc32/setjmp-common.S (SAVE_GP): Define
macro conditional on [__SPE__ || (__NO_FPRS__ && !_SOFT_FLOAT)].
(__sigsetjmp): Use SAVE_GP to save GPRs.
* sysdeps/powerpc/powerpc32/Makefile [$(with-fp) = no] (+cflags):
Do not append -msoft-float.
[$(with-fp) = no] (sysdep-LDFLAGS): Likewise.
