glibc/sysdeps/s390/fpu/s_fmaf.c
Joseph Myers 313ba4630f Use libm_alias_float for s390.
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.
