I'm convensed we need to support /compat/freebsd-i386 if we have any
hopes of using 32-bit ports on FreeBSD/AMD64.

We still want to install the 32-bit shared libs as we do today - they
aren't fully ABI compatable with FreeBSD/i386 (because we do certain
optimizations) - but they don't need to be as they just need to be ABI
and API compatable with the published extern interfaces.
