Currently, I'm just trying to test out the cross-build, but the
final result is that I want to use nanobsd to create embedded
images, all from amd64.  Multiple people here want to be able
to do that.  I don't really want to have to setup a jail
(with LDAP logins, cause that's what we use) or even an x86
box to do that.

I thought even ARM and MIPS cross-builds worked, I didn't
expect amd64->i386 problems.

I think I will ask on -current, as that is also an option
for us.
