Use libm_alias_double for sparc.

Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes sparc libm function implementations use
libm_alias_double to define function aliases (with consequent
simplification where compat symbol handling is now done by those
macros rather than locally in architecture-specific code).

Tested with build-many-glibcs.py for all its sparc configurations that
installed stripped shared libraries are unchanged by the patch.
