This is probably still a manifestation of
https://github.com/ClangBuiltLinux/continuous-integration/issues/262
because rekicking the tests usually fixes it.

We should probably just disable the torture tests like we do for x86_64
for CI because we do not have access to QEMU 5.0.0 where this should be
fixed. I believe it is slated for 4.2.1 as well but we still have to
wait for that to be updated and packaged in Ubuntu.
