Do not define -mlong-double-128 on ppc when --without-fp specified?

OK.

Why should I bother with the nofpu implementation since libc/soft-fp
works great?  What's different between the nofpu implementation and
libc/soft-fp and why powerpc needs its own nofpu implementation
whereas libc/soft-fp works for other machines without fpu like MIPS
and ARM?
