- Authentication-results: sourceware.org; auth=none
This patch adds support for defining strfromf32 as an alias of
strfromf when _Float32 support is enabled.
Tested for x86_64; also tested with build-many-glibcs.py in
conjunction with other _Float32 changes. Committed.

* stdlib/strfromf.c: Include <bits/floatn.h>.
[__HAVE_FLOAT32 && !__HAVE_DISTINCT_FLOAT32] (strfromf32): Define
and later undefine as macro and define as weak alias.
