Support strtof128 etc. aliases.
This patch adds support for building strtof128, wcstof128, strtof128_l and wcstof128_l as aliases, in the case of __HAVE_FLOAT128 && !__HAVE_DISTINCT_FLOAT128. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. Also tested together with changes to enable float128 aliases. * stdlib/strtold.c: Include <bits/floatn.h> [__HAVE_FLOAT128 && !__HAVE_DISTINCT_FLOAT128] (strtof128): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [__HAVE_FLOAT128 && !__HAVE_DISTINCT_FLOAT128] (wcstof128): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR]. * sysdeps/ieee754/ldbl-128/strtold_l.c [__HAVE_FLOAT128 && !__HAVE_DISTINCT_FLOAT128] (strtof128_l): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [__HAVE_FLOAT128 && !__HAVE_DISTINCT_FLOAT128] (wcstof128_l): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR]. * sysdeps/ieee754/ldbl-64-128/strtold_l.c: Include <bits/floatn.h>. [__HAVE_FLOAT128 && !__HAVE_DISTINCT_FLOAT128] (strtof128_l): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [__HAVE_FLOAT128 && !__HAVE_DISTINCT_FLOAT128] (wcstof128_l): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR].
