I'll save you the effort, since it was easy to add the rest after
getting the first one incorporated into our build.

The set above are in code review at https://reviews.freebsd.org/D1224.
It adds a WITH_ELFTOOLCHAIN_TOOLS knob to enable building them instead
of binutils. I have a -current VM built with that enabled and it
passes basic sanity tests.

I know that at elftoolchain is missing some required functionality for
MIPS at least, but I don't think it'll be hard to add. What I'd like
to do is commit the change in D1224 after a little more refinement,
then call for broader testing and a ports exp run. We can enable
WITH_ELFTOOLCHAIN_TOOLS by default on a per-architecture basis until
it works properly everywhere.
