libgfortran: Fix up LIBGFOR_CHECK_FLOAT128 [PR106137]
My recent gfortran + libgfortran patch apparently broke (some?) aarch64
builds. While it is desirable to use just _Float128 rather than __float128,
we only want to use it (and e.g. define HAVE_FLOAT128) on targets where
_Float128 is supported and long double isn't IEEE quad precision.
Which is targets that support __float128 type which we have been testing
for before - _Float128 is supported on those targets and on targets where
long double is IEEE quad precision.
So, the following patch restores check for whether __float128 is supported
into the LIBGFOR_CHECK_FLOAT128 check which determines whether
HAVE_FLOAT128 is defined or whether to use libquadmath, so that e.g. on
aarch64 where long double is IEEE quad we don't do that.
