Support strfromf64x alias.
This patch adds support for defining strfromf64x as a function alias
(of strfroml or strfromf128, as appropriate) when _Float64x is
supported.
Tested for x86_64, including in conjunction with _Float64x support
patches, and also tested build for other configurations (in
conjunction with _Float64x support patches) with build-many-glibcs.py
to cover the various different files needing updating to define these
aliases.
* stdlib/strfroml.c: Always include <stdlib.h>.
[__HAVE_FLOAT64X_LONG_DOUBLE] (strfromf64x): Define and later
undefine as macro and define as weak alias.
* sysdeps/ieee754/float128/strfromf128.c: Include <bits/floatn.h>.
[__HAVE_FLOAT64X && !__HAVE_FLOAT64X_LONG_DOUBLE]: Include
<stdlib.h>.
[__HAVE_FLOAT64X && !__HAVE_FLOAT64X_LONG_DOUBLE] (strfromf64x):
Define and later undefine as macro and define as weak alias.
