Joseph Myers 6d9b0b5a22 Fix powerpc64le problem from last ldbl-opt patch.
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.
