There is a problem with libiberty and utils because GCC have their
feet stuck in the ice
Plus the libiberty master *is* gcc, so you can't apply the patches to
just the src side anyway. The libiberty in src is a "mere copy" of
the one in gcc. You must apply libiberty patches to gcc either at the
same time or before applying them to src (and now is a bad time to
change gcc's libiberty).
Utils is not part of gcc.
(unless src, again splits off from GCC, but I suspect here we don't
want to).
Sorry, won't happen for libiberty.
