41 <para os="u1">The powerpc (32) architecture is expected to fail the
42 check-textrel tests because it cannot protect some elf segments in
43 shared libraries from being executable and writable. Using the default
44 64-bit compiler means the test runs as <literal>__powerpc64__</literal>
45 which is <emphasis>not</emphasis> expected to fail. The problem only exists
46 in 32-bit, the 64-bit ABI allows the segments to be protected.</para>
