ppc/siteinfo: Fix differences between musl and glibc

There is a key difference between glibc and musl when it comes to
ppc/ppc64 and that is that musl does not support 128-bit long IBM doubles format
it only supports 128-bit long double IEEE format on ppc64 alone.
this change ensures that we account for this change, so far we have been
doing it a bit wrong for ppc/musl case.
