Tested that with four runs on powerpc64-linux, four configs each time;
test-summary
shows the same in all cases.  Many lines have moved compared to without
the patch, but that cannot be helped.  Okay for mainline?

This is still open.


I also did some timings for make -j60 -k check, same -m64,-m32,-m32/-mpowerpc64,
-m64/-mlra configs.  A run takes 65m, is effectively 42x parallel, and has 15%
system time.
