To build an i386 kernel on an amd64 host do this:

cd /usr/src (or some other tree)
make TARGET=i386 kernel-toolchain
make TARGET=i386 buildkernel
make TARGET=i386 installkernel DESTDIR=/some/place

And your i386 kernel will end up in /some/place/boot/kernel/kernel.  (You can 
set things like KERNCONF to pick an alternate kernel config just as with 
normal 'make buildkernel'.)
