Subject: hypotf-ieee: Work around test failure on OSF/1 and native Windows.

* m4/hypotf-ieee.m4: New file.
* m4/hypotf.m4 (gl_FUNC_HYPOTF): If gl_FUNC_HYPOTF_IEEE is present,
test whether hypotf works with mixed NaN and Infinity arguments.
Replace it if not.
* modules/hypotf-ieee (Files): Add m4/hypotf-ieee.m4.
(Depends-on): Add hypot-ieee.
(configure.ac): Invoke gl_FUNC_HYPOTF_IEEE.
* doc/posix-functions/hypotf.texi: Mention the hypotf-ieee module.
