Use libm_alias_float for sparc.

Use libm_alias_float for sparc.

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.
