    Don't build readline/libreadline.a, when --with-system-readline is supplied
    
    https://sourceware.org/bugzilla/show_bug.cgi?id=18632
    
    The bundled libreadline is always built, even if the system is
    ./configure'd --with-system-readline and the build libreadline.a is not
    used.
    
    Proposed patch:
    
    Fix ./configure.ac not to proceed readline/, when --with-system-
    readline is provided
