Use libm_alias_ldouble in sysdeps/i386/fpu [committed]

Subject: Use libm_alias_ldouble in sysdeps/i386/fpu [committed]
Authentication-results: sourceware.org; auth=none
This patch continues the preparation for additional _FloatN / _FloatNx
function aliases by using libm_alias_ldouble for sysdeps/i386/fpu long
double functions, so that they can have _Float64x aliases added in
future.

Tested for x86_64 (which includes some of these implementations) and
x86, including build-many-glibcs.py tests that installed stripped
shared libraries are unchanged by the patch.  Committed.
