Continuing the preparation for additional _FloatN / _FloatNx function aliases, this patch makes alpha libm function implementations use libm_alias_float macros to define function aliases. In the case of the ABI compatibility for complex functions, libm_alias_float_other is used, with the cfloat_versions macro adjusted to take a function name argument without the trailing 'f' to facilitate this, and cfloat_versions dealing with calling libm_alias_float_other (except for clog10f, which doesn't use that macro because of the complexity associated with __clog10f also being exported). Tested with build-many-glibcs.py for alpha-linux-gnu that installed stripped shared libraries are unchanged by the patch. * sysdeps/alpha/fpu/cfloat-compat.h: Include <libm-alias-float.h>. (cfloat_versions): Take function argument without trailing 'f'.
