Thanks for tracking this down. This tends to be a rare problem, because
usually packages get built with roughly the same versions of
dependencies. riscv64 was lagging behind a a bit and delayed some
builds. Its task queue is now below 3 hours.

The question I have here is whether the cure is better than the disease
here. If we simply remove the version, there is no flagging of different
versions being used. Therefore, bugs can become subtly
architecture-specific. This may make debugging them harder. We don't
technically need the version information as it is recorded in the
.buildinfo.

So another way to resolve this would be asking the release team for a
binNMU with the expectation that such a version difference is rare.

You're the domain expert here, so I trust your choice here.
