Use libm_alias_ldouble in sysdeps/i386/fpu. 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. * sysdeps/i386/fpu/e_expl.S: Include <libm-alias-ldouble.h>.
