Use libm_alias_double for s390.
Continuing the preparation for additional _FloatN / _FloatNx function aliases, this patch makes s390 libm function implementations use libm_alias_double to define function aliases. This allows sysdeps/unix/sysv/linux/s390/fpu/s_fma.c to be removed, as libm_alias_double handles symbol versioning for long double compat symbols. Tested with build-many-glibcs.py for s390-linux-gnu and s390x-linux-gnu that installed stripped shared libraries are unchanged by the patch. * sysdeps/s390/fpu/s_fma.c: Include <libm-alias-double.h>. [!__fma] (fma): Define using libm_alias_double. * sysdeps/unix/sysv/linux/s390/fpu/s_fma.c: Remove.
