Since we install Python modules under $VIRT_PREFIX, we need to set $PYTHONPATH or the interpreter won't be able to locate them. This is currently being done per-worker in the Jenkins Web interface. However, now that we've introduced Python 3 builds, depending on the project and the OS, we might be using any of Python 2.7, 3.4, 3.5 and 3.6, which means we can't have a single $PYTHONPATH anymore: in particular, while it's okay to have non-esisting directories in $PYTHONPATH, we have to make sure that a Python 3 interpreter will never try to use a Python 2 module and vice versa. To solve the issue, we use a fairly large hammer: we set $PYTHONPATH at the job level, and include all reasonable minor versions for the Python major version (pyver) the job is using, even if they don't yet exist.
