ppc64 != ppc64el, or am I missing something?

seccomp support has been enabled on ppc64el since almost a year:

https://anonscm.debian.org/cgit/pkg-systemd/systemd.git/commit/?id=7a1805b4e89f3545cd110d6e6ed2125fe946e685

Do we have any ppc/powerpc porters which can help us in that regard and
let us know if seccomp is working on that architecture:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=853755 (ppc64el)
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=853940 (powerpc)
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=852811 (ppc64)

Could it be that older versions were already broken but it simply went
unnoticed because none of the sandboxing features were used in the
.service files?

Erwan, could you try 232-1 from snapshots.debian.org and see if the
problem is reproducible there?
