    sh: Rip out special unknown machvec.
    
    This kills off the BareCPU board as a "special" machvec, rather,
    we leave this as a default for when no other vector is available,
    or when we want to use it in combination with other vectors for
    testing with generic ops. As sh_mv is copied out anyways (or
    overloaded when an alternate vector is explicitly selected), this
    doesn't consume any additional memory.
    
    The generic machvec can be forcibly selected with sh_mv=generic,
    or by not having any other boards enabled.

-         "Bare CPU" aka "unknown" means an SH-based system which is not one

-         system doesn't already know what it is.  You get a machine vector
-         without any platform-specific code in it, so things like the RTC may
-         not work.
