head -r347492 changed what made head -r346588 a good
test case for the mtx_lock issue: it removed use of
the illegal instructions (as far as pre-power6 processors
are concerned).

So, either using the range that is a test-case on such
older power/powerpc64 or other means of inducing a test
case is now needed.
