Enable the building of the library on s390 and specify the behavior of
the icache-hygiene test. The testsuite runs relatively clean. Only one
major issue and I've reported it upstream.

Note, even with the icache-hygiene update, I'm seeing periodic failures
with mmap() 1 giving ENOMEM. I'm not sure what's going on there yet.
And, iirc, task-size-overrun takes a *long* time to finish.
