<!-- items n,o,p here are now the master, not multilib, because

    <para os="o">The Glibc test suite is highly dependent on certain functions of
    the host system, in particular the kernel. In general, the Glibc test
    suite is always expected to pass. However, in certain circumstances,
    some failures are unavoidable. This is a list of the most common
    issues:</para>
