Tentative patch

I'm not sure this will work properly, I think in C _Float128 is a distinct
type, so in _Generic it will probably not match __float128.
I think libgfortran uses __float128, not _Float128.
Shouldn't the __float128 stuff be guarded with
defined(GFC_REAL_16_IS_FLOAT128) || defined(HAVE_GFC_REAL_17)
