    <note><para>The test time for libtool can be reduced significantly on a
    system with multiple cores.  To do this, append
    <command>TESTSUITEFLAGS=-j&lt;N&gt;</command> to the line above.  For
    instance, using -j4 can reduce the test time by over 60
    percent.</para></note>

    <para>Five tests are known to fail in the LFS build environment due
    to a circular dependency, but all tests pass if rechecked after 
    automake is installed.</para>
