Continuing the preparation for additional _FloatN / _FloatNx function aliases, this patch makes sparc libm function implementations use libm_alias_float to define function aliases. Tested with build-many-glibcs.py for all its sparc configurations that installed stripped shared libraries are unchanged by the patch. * sysdeps/sparc/sparc32/fpu/s_copysignf.S: Include <libm-alias-float.h>.
