Fix ldbl-opt/s_clog10l.c libm_alias_ldouble_other usage.

Testing with changes to enable _Float128 function aliases shows that
the libm_alias_ldouble_other usage in ldbl-opt/s_clog10l.c does not in
fact work, because __clog10l is defined with long_double_symbol rather
than as a normal C alias.  This patch fixes this by renaming the
__clog10l__internal alias (not strictly necessary, but avoids a hack
with "__clog10l_interna" / "__clog10l__interna" as first argument to
libm_alias_ldouble_other) and using the renamed alias when calling
libm_alias_ldouble_other.

Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanges by the patch.  Also tested in conjunction with
patches to enable _Float128 function aliases.

	* sysdeps/ieee754/ldbl-opt/s_clog10l.c (__clog10l__internal):
	Rename to __clog10_internal_l.
	(__clog10_internal_l): Define aliases using
	libm_alias_ldouble_other instead of using libm_alias_ldouble_other
	with __clog10.
