commit d5632bcfd465b7f980c0e0d2ef0d3a7438c98878

    Sync toplevel configure with upstream GCC.
    
    This fixes a problem, where libgloss wouldn't be built for ARC processors,
    even though it is actually supported. The original patch that introduced
    support for ARC in libgloss hasn't been submitted to GCC maillist, hence
    when top-level configure has been synced with GCC - this libgloss patch has
    been effectively reverted.
    
    Libgloss support for ARC has been accepted in GCC:
