We really need newer binutils in the tree.

And we need a way to compiler gplv3 binutils into the system for folks
that can do that without consequences...  But many modern processors
need to have the gplv3 version of binutils and that will be a
continuing problem.  One advantage of FreeBSD is its integration,
rather than having to play version whack-a-mole like you do with
embedded Linux.
