    tools/debugger: fix make distclean
    
    "make distclean" will complain that "-c" is no supported flag for make.
    
    Fix that by using "-C".
    
    The error has been present for a long time, but it was uncovered only
    recently.
    
    Fixes: 2400a9a365c5619 ("tools/debugger: Allow make to recurse into 
debugger/")
    Fixes: f9c9b127753e9ed ("tools: fix make distclean")
