*[Temporarily disable building with `build2` and `build` as the jenkins user](https://salsa.debian.org/qa/jenkins.debian.net/commit/e76b96c6). This was an attempt to diagnose a path-variation issue.
*[Also call `printenv` before the builds to diagnose path issue](https://salsa.debian.org/qa/jenkins.debian.net/commit/bed37f55).
*[Always force PATH to match `makechrootpkg`](https://salsa.debian.org/qa/jenkins.debian.net/commit/8d2d1b29), else Arch Linux builds vary as the include the current PATH in the build results.
*[Increase timeout for running `diffoscope` to one hour](https://salsa.debian.org/qa/jenkins.debian.net/commit/628e4da5).
*[Set PATH to match `makechrootpkg`](https://salsa.debian.org/qa/jenkins.debian.net/commit/8d2d1b29).
