Let me quote what I wrote in #853940

The relevant upstream bug report is
https://github.com/systemd/systemd/issues/4575

That seccomp code is admittedly over my head. I guess it would be best
if you take this issue upstream and talk directly to them, letting them
know that the changes from #4575 apparently caused a regression on powerpc.

As for the stretch release, I'm currently undecided what the best course
of action is. Disabling the sandboxing features/Seccomp on ppc* seems
like an option.

Adrian said he wanted to look into this over the weekend. So maybe we
know more then.
