Fixed just in the sense that the testing is more parallelized.
I've been using make -jN -k check for more than a decade and I don't
remember problems with that, mudflap tests are flaky and tend to fail
more often under load, but mudflap has only been added in 4.0.
Of course the N keeps changing over time, but currently testing certainly
works with -j48 that I'm using daily.
