I have upgraded our build environment for https://github.com/datalad/git-annex from bullseye (now old stable). to bookworm (now stable). Docker images are at https://hub.docker.com/repository/docker/datalad/buildenv-git-annex/tags (prior ones at https://hub.docker.com/repository/docker/datalad/buildenv-git-annex-buster/tags) .
The git-annex (`10.20230828+git2-g50300a47fe-1~ndall+1`) has built fine and all testing passed, but one [extra test has failed](https://github.com/datalad/git-annex/actions/runs/6029623735/job/16366573859#step:6:33):
```

>> strace -f git-annex version
>> tee /dev/fd/2
>> wc -l
>> awk '/libpcre.*so.*ENOENT/{print}'

```
[previously (`10.20230828-1~ndall+1`was the last successful build) it was just 3](https://github.com/datalad/git-annex/actions/runs/6003338461/job/16282128434):
```

```
where those 3 extra (identical) looks up are coming from now?
PS Since not critical, I will workaround for now by raising max count to 7.
