[PATCH] Fix FCFLAGS handing in libgfortran/configure.ac

[Richard Guenther]

The current setup doesn't allow overriding of compile-flags with
setting FCFLAGS.  Fixed by moving needed flags to AM_FCFLAGS.

Ok for mainline/4.0?

Thanks,
Richard.

	* configure.ac: Use AM_FCFLAGS for extra flags, not FCFLAGS.
	* configure: Regenerate.
