Thank you Joseph.

I made it behave like:

	@section References for other languages

	@xref{Top, GNAT Reference Manual, About This Guide, gnat_rm,
	GNAT Reference Manual}, for information on standard
	conformance and compatibility of the Ada compiler.

elsewhere in standards.texi.

OK for branch?

	* doc/invoke.texi: Add xref for libitm.
