I bootstrapped yesterday's SVN on this platform:

  Linux fencepost 2.6.16.29-xen #1 SMP Wed Dec 6 07:32:36 EST 2006 x86_64 GNU/Linux

> For a patch like this only the libiberty testsuite need be run.

After a successful bootstrap, I typed "make -C libiberty check", and
the test ran to completion without any errors.

Here's again the patch I suggest (this time including the removal of 2
obsolete Awk scripts).  As I don't have write access, could someone
please commit it?

Thanks.

	* Makefile.in (needed-list): Target removed (not used in GCC
	3.0 and later).  All references deleted.
	(mostlyclean): Remove references to needed.awk and needed2.awk.
