This patch fixes a problem on powerpc64le that I missed in initial testing of my last patch to ldbl-opt. In the specific case of powerpc64le, the weak aliases for exp10l and remainderl do not get defined in the generic wrappers because of how those wrappers undefine and redefine weak_alias. This patch restores those aliases in the ldbl-opt code. Tested (compilation only) for powerpc64le with build-many-glibcs.py. * sysdeps/ieee754/ldbl-opt/w_exp10l_compat.c [LIBM_SVID_COMPAT && !LONG_DOUBLE_COMPAT (libm, GLIBC_2_1)] (weak_alias): Undefine and redefine. [LIBM_SVID_COMPAT && !LONG_DOUBLE_COMPAT (libm, GLIBC_2_1)] (exp10l): Define as weak alias. * sysdeps/ieee754/ldbl-opt/w_remainderl_compat.c [LIBM_SVID_COMPAT && !LONG_DOUBLE_COMPAT (libm, GLIBC_2_0)] (weak_alias): Undefine and redefine. [LIBM_SVID_COMPAT && !LONG_DOUBLE_COMPAT (libm, GLIBC_2_0)] (remainderl): Define as weak alias.
