Support defining strfromf32 alias.

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.

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