I have tried building mariadb with several flag combination and each
time it fails. I have tried `--max-jobs=2 --cores=8`, `--max-jobs=1
--cores=2` and `--max-jobs=1 --cores=1`.

On an x86_64 computer when I run `guix build --no-substitutes
--max-jobs=1 --cores=1 --keep-failed mariadb` I get this error.


```

`guix describe` outputs:

The build log says that this one test is failing:
perfschema.socket_connect

The build log is attached.
