This patch fixes ldbl-opt code to use generic libm alias macros in preparation for getting _FloatN / _FloatNx aliases where appropriate. Four functions are affected, that undefine and redefine alias macros before including the implementations they wrap in such a way that _FloatN / _FloatNx aliases would not appear. s_clog10l.c undefines and redefined declare_mgen_alias, so just needs a libm_alias_ldouble_other call added. w_exp10l_compat.c undefines and redefines weak_alias, but in fact does not need to do so, since math/w_exp10l_compat.c uses libm_alias_ldouble and does not use weak_alias other than through that, so the undefines and redefines of weak_alias are removed. w_lgamma_compatl.c and w_remainderl_compat.c are made to use libm_alias_ldouble_other in conjunction with restoring the original definition of weak_alias so this is effective. Tested with build-many-glibcs.py. Installed stripped shared libraries are unchanged by this patch. * sysdeps/ieee754/ldbl-opt/s_clog10l.c: Use libm_alias_ldouble_other. * sysdeps/ieee754/ldbl-opt/w_exp10l_compat.c (weak_alias): Do not undefine and redefine. [LIBM_SVID_COMPAT && !LONG_DOUBLE_COMPAT (libm, GLIBC_2_1)] (exp10l): Do not define here. * sysdeps/ieee754/ldbl-opt/w_lgamma_compatl.c [BUILD_LGAMMA] (weak_alias): Undefine and redefine. [BUILD_LGAMMA]: Use libm_alias_ldouble_other. * sysdeps/ieee754/ldbl-opt/w_remainderl_compat.c [LIBM_SVID_COMPAT] (weak_alias): Undefine and redefine here. [LIBM_SVID_COMPAT]: Use libm_alias_ldouble_other.
