I've pushed a trini/add-libc-overrides-2 branch with the following
changes:
- Change PREFERRED_LIBC to LIBC
- Fold fixing up minimal/minimal-uclibc into the commit that brings in
  the libc inc file.
- Re-order commits so that everything is functional from commit to
  commit.

I'm now looking for ack's to pull this branch into .dev
