<!-- On one system the -j4 improvement is 167s - 46s = 121s (72.46%) -->
<note><para>The test time for Tar 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

run because LFS lacks selinux, but will be skipped if the host kernel does
not support extended attributes on the filesystem used for building LFS.</para>
