Use libm_alias_double for dbl-64 fma.
This patch makes dbl-64 fma use libm_alias_double. The ldbl-opt version is removed. The sparc32 version no longer needs to handle compat symbols, while alpha needs a new wrapper to avoid getting the ldbl-128 version (where ldbl-opt is earlier in the list of sysdeps directories, so previously fma came from there). Tested for x86_64, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/ieee754/dbl-64/s_fma.c: Include <libm-alias-double.h>. (fma): Define using libm_alias_double. * sysdeps/ieee754/ldbl-opt/s_fma.c: Remove file. * sysdeps/sparc/sparc32/fpu/s_fma.c: Do not include <math_ldbl_opt.h>. (fmal): Do not define as compat symbol here. * sysdeps/alpha/fpu/s_fma.c: New file.
