    Remove two more files in gdb "distclean"
    
    The recent work to have gdb link via libtool means that there are a
    couple more generated files in the build directory that should be
    removed by "distclean".
    
    Note that gdb can't really fully implement distclean due to the desire
    to put certain generated files into the distribution.  Still, it can
    get pretty close.
