Do not use wildcard symbol names for public versions in Versions files.
As noted in
<https://sourceware.org/ml/libc-alpha/2012-12/msg00240.html>,
stdlib/Versions and wcsmbs/Versions list some functions as
__strto*_internal and __wcsto*_internal rather than explicitly listing
the symbols to be exported (so any new internal function matching one
of those patterns would be wrongly added to version GLIBC_2.0), which
seems like a bad idea.  This patch changes those files to list the
exported symbols explicitly.  There are still entries in
sysdeps/nacl/Versions for __nacl_irt_*, but as GLIBC_PRIVATE symbols
that seems less significant.

Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged by the patch.

	* stdlib/Versions (__strtod_internal): List explicitly, not as
	wildcard.
	(__strtof_internal): Likewise.
	(__strtold_internal): Likewise.
	(__strtol_internal): Likewise.
	(__strtoll_internal): Likewise.
	(__strtoul_internal): Likewise.
	(__strtoull_internal): Likewise.
	(__strtoq_internal): Likewise.
	(__strtouq_internal): Likewise.
	* wcsmbs/Versions (__wcstod_internal): Likewise.
	(__wcstof_internal): Likewise.
	(__wcstold_internal): Likewise.
	(__wcstol_internal): Likewise.
	(__wcstoll_internal): Likewise.
	(__wcstoul_internal): Likewise.
