Actually I'd really love for a way to do the outter loop in parallel.
Due to -j messing up error output too much, I'd like to have the work for
each platform going in parallel instead.  E.g.:

    make universe for i386 only &
    make universe for powerpc only &
    make universe for sparc64 only &
    make universe for amd64 only &
    make universe for alpha only &
    make universe for ia64 only &
