    ppc4xx: Clean up 440 exceptions handling · efa35cf1

    - Introduced dedicated switches for building 440 and 405 images required
      for 440-specific machine instructions like 'rfmci' etc.
    
    - Exception vectors moved to the proper location (_start moved away from
      the critical exception handler space, which it occupied)
    
    - CriticalInput now serviced (with default handler)
    
    - MachineCheck properly serviced (added a dedicated handler and return
      subroutine)
    
    - Overall cleanup of exceptions declared with STD_EXCEPTION macro (unused,
      unhandled and those not relevant for 4xx were eliminated)
    
    - Eliminated Linux leftovers, removed dead code
