Indeed, compiler support for float128 needs VSX.  Once float128 support is
enabled in glibc, builds for processors that don't provide VSX will fail,
but will fail late.  My intention with this patch is to fail as early as
possible, and, since powerpc64le support starts with power8, I added this
check to the powerpc64le-specific configure script.
