Joseph Myers - Dec. 6, 2017, 10:46 p.m.
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.

2017-12-06  Joseph Myers  <joseph@codesourcery.com>

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