Continuing the preparation for additional _FloatN / _FloatNx function aliases, this patch makes an s390 libm function implementation use libm_alias_float to define function aliases. 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_fmaf.c: Include <libm-alias-float.h>. [!__fmaf] (fmaf): Define using libm_alias_float.
