    Reapply "Don't build readline/libreadline.a, when --with-system-readline is supplied"
    
    Commit 228cf97dd3c8 ("Merge configure.ac from gcc project") undid the
    change originally done in commit 69961a84c9b ("Don't build
    readline/libreadline.a, when --with-system-readline is supplied").
    Re-apply it.
