I committed a fix for this in r219648, so at least:
- gcc -m32 uses the correct library path to find crt startup objects
- ld uses the correct library path to find libraries
- simple 'hello world' type programs link and run

However, this does *not* solve the problem completely, as the system
headers in /usr/include/machine will still be amd64 specific.  This
can result in various kinds of brokenness.  Please be careful.

If you want to reliably build i386 executables, you should still use a
native i386 installation.
