libiberty patch

[Jason Merrill]

Someone pointed out that libstdc++ was including some bits from libiberty
that are LGPL, and furthermore don't have any reason to be in libstdc++.
The only things that should be included are functions libstdc++ actually
uses, and perhaps functions needed for ISO C compliance.

Applied.

	* Makefile.in (needed-list): Only include stuff we actually need
	for libstdc++.
