@Thomas, will that survive our test framework already, or do we have to
wait for the debain11 changes?

Alex' update to the container has already been merged:

https://gitlab.com/qemu-project/qemu/-/commit/89767579cad2e371b

... and seems like it's working in Travis on s390x, too:

https://app.travis-ci.com/github/huth/qemu/jobs/564188977#L12797

... so it seems like it should be OK now (considering that we drop support for the old Ubuntu version 18.04 in QEMU 7.1, too).

Looks like I spoke a little bit too soon - some of the CI pipelines are still using Debian 10 for running the TCG tests, and they are failing with these patches applied:

https://gitlab.com/thuth/qemu/-/jobs/2238422870#L3499

Thus we either need to update the CI jobs to use Debian 11, or use handcrafted instruction opcodes here again...
