Add system dependent behavior to myrbuild.

    It probes the OS it runs on now, and changes the commands to
    the appropriate ones. For now, that means changing the linker
    command line to specify the OSX version.

    In the future, when we support multiple architectures, it will
    include probing the architecture as well.
