Or just symlinking it; works fine for me.  I was even able to upgrade
the chroot from source (from within itself) by adding MACHINE=i386 and
MACHINE_ARCH=i386 to /etc/make.conf and using the following patch:

In my case, the chroot is actually the NFS-exported file system for my
diskless crash boxen (which are the only 32-bit systems I have left)
