"make check-qtest-ppc64" fails for me, too.

Thomas, this seems to be again the well known timing problem
in tests/prom-env-test.c. The time for the test had been
changedfrom 30 s to 10 s to 120 s in the past.

For TCI, even that latest value isnot sufficient when
testing with pseries. Of course that also depends on other
parameters (speed of test machine, compilerflags).

In my test pseries took nearly 5 minutes, so the test passes
when the loop upper limit is increased to 30000.

Is there a better way to handle this test? Why does pseries
still need much more time than the other machines
(not only with TCI)?
