It consistently fails when ran on a build machine within the
reproducible build environment, so move it out of there, so
that we can run the fast suite at build time when packaging.

This test is quite simple.
Surprising that it consistently fails.

It is very weird. I think it times out after the fork().

Repro test environment:

https://salsa.debian.org/salsa-ci-team/pipeline/

I am not familiar with this CI.
Where can we find the logs of such a failure?

It does various scramblings to ensure the produced binaries are bit-by-
bit identical despite changes like number of CPUs, time of the day,
timezone, filesystem, locale, etc.

Not much useful info in the logs unfortunately, despite the verbose
run.
