    debug: Mark libSegFault.so as NODELETE
    
    The signal handler installed in the ELF constructor cannot easily
    be removed again (because the program may have changed handlers
    in the meantime).  Mark the object as NODELETE so that the registered
    handler function is never unloaded.
