    NetBSD build.sh runs great on FreeBSD, when building NetBSD sources
    that is :-).

    I know that cross builds for i386 from amd64 work well enough.
    However, we[*] was unable to get a full cross build for i386 world
    seutp on my amd64 machine when last I tried.

    [*] tried to setup a dual amd64 box as our build server for our
    embedded FreeBSD/i386 product. It was quite a bit more complicated
    than just a normal cross build, but there were many issues that our
    (both FreeBSD and our company's) build system paper over for a few
    edge cases that seem to not matter...
