I've been wanting to do this for yonks. Approved for mainline, unless DJ or
Alex objects. Give them a day or two.

However, it *will* be somewhat confusing for developers that the location
of the build has moved; please post an announcement to gcc@gcc.gnu.org if
this goes in, explaining the new presence of host-i686-pc-linux-gnu, etc.
