Support strfromf128 alias.
This patch adds support for building strfromf128 as an alias of strfroml, 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/strfroml.c: Include <bits/floatn.h>. [__HAVE_FLOAT128 && !__HAVE_DISTINCT_FLOAT128] (strfromf128): Define before include of <stdlib.h> and undefine afterwards, then define as weak alias.
