Since the commit [1] the janet package started failing on the
autobuilder when using musl libc:
```

```
The commit [2] introduced the issue in v1.35.0, the `strerror` function
has different definition on glibc compared to musl. This issue has been
addressed in commit [3]. This patch add the upstream commit [3].
