    If you do that, then things like randconfigs will randomly break if you
    happen to use a toolchain targetted specifically at i386 or so.

    randconfigs are pretty useful for testing, it would be nice to have a
    facility to keep these working without having to have a script grep the
    .config to figure out which toolchain prefix to use.

    This is one of the things I've been wondering about with an sh/sh64
    unification, as we have no option but having completely different
    toolchains, and CONFIG_64BIT=y won't work there when they are both
    using a 32-bit ABI.
