    Remove m68k-openbsd support
    
    This removes m68k-openbsd as a valid configuration, according
    to openbsd.org m68k-openbsd [on the mac] was discontinued after
    the 5.1 release.  The configuration is also not (or no longer)
    supported by gas and GNU ld so I could not figure whether it is still
    a.out (I suspect it is).  But first and foremost the target only supports
    STABS as a debugging format.
