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.
