In several cases, we call `python` explicitly. On many modern operating systems (e.g., Ubuntu 22.04), this command no longer exists, and if it does, it's often an alias to python3. Because the python3 executable has been around for so long, simply using that directly (instead of, e.g., autodetecting the OS preferences) is a simple fix that immediately allows building bitfiles, e.g. for the B2xx series, on more recent OSes.
