Bug#1023442: systemd FTBFS: python3-pyparsing:native no longer satisfiable

Source: systemd
Version: 251.4-3
Severity: serious

systemd fails to build from source, because dpkg-checkbuilddeps now
rejects python3-pyparsing:native as it got tagged Multi-Arch: foreign. I
think this is a bug #1023438 in dpkg-checkbuilddeps, but short term,
this will have to be fixed in systemd by dropping :native from
python3-pyparsing.

I also think this partially is a failure on Jan's side. He added the
:native annotation without checking whether python3-pyparsing should
have been marked Multi-Arch: foreign first. I also wondered why Jan
needs this change in the first place. Why do you run cross builds
without nocheck?
