Works for me:
[10:55:58] Testing complete. Ran 201 tests: passed: 165, skipped: 36
[10:55:58] Elapsed time: 21.268s total, 0.003s configuring, 4.009s
building, 16.967s running

Side note:
I ran into an unrelated bug where running on QEMU in general seems to
hang when you try to filter to a test suite that doesn't exist.
I've confirmed it happens on i386 before this patch, and it at least
also happens on x86_64.
