    gdb: add some additional debug output in remote.c
    
    I needed more debug output from:
      remote_target::select_thread_for_ambiguous_stop_reply
    I thought this would be useful for others too.
    
    gdb/ChangeLog:
    
            * remote.c (remote_target)
            <select_thread_for_ambiguous_stop_reply>: Add additional debug
            output.
