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
