Use libm_alias_double in ldbl-128, ldbl-96 fma.
This patch makes the ldbl-128 and ldbl-96 implementations of fma use
libm_alias_double.
Tested for x86_64, and tested with build-many-glibcs.py that installed
stripped shared libraries are unchanged by the patch.
* sysdeps/ieee754/ldbl-128/s_fma.c: Include <libm-alias-double.h>.
[!__fma] (fma): Define using libm_alias_double.
* sysdeps/ieee754/ldbl-96/s_fma.c: Include <libm-alias-double.h>.
[!__fma] (fma): Define using libm_alias_double.
