Comment:
The name of the library directory is not always the same. It's `build/lib` for pure-Python packages and `build/lib.<arch>` for packages with compiled extensions.

That said, this is unnecessary here for two reasons:
1. All you need to do is add `python3-pytest` to `checkdepends` and let the default check run.
2. 99/101 tests are skipped because there is no functional clipboard in the environment. If you can't get a working clipboard in the test environment, you might as well just `make_check=no` because all of the real tests are ignored anyway.
