    <para os="u1">The powerpc (32) architecture is expected to fail the
    check-textrel tests because it cannot protect some elf segments in
    shared libraries from being executable and writable. Using the default
    64-bit compiler means the test runs as <literal>__powerpc64__</literal>
    which is <emphasis>not</emphasis> expected to fail. The problem only exists
    in 32-bit, the 64-bit ABI allows the segments to be protected.</para>

    <para os="u2">Other distributions alter gcc to default to 32-bits and
    so do not see this failure.  Whether they then test correctly on 64-bit
    libraries is not our problem.</para>
