python34 test won't run without python3-dev

When attempting to run:
tox -epy34
I get the following:
   ext/_yaml.c:8:22: fatal error: pyconfig.h: No such file or directory
     #include "pyconfig.h"
                          ^
    compilation terminated.

This is fixed by installing python34

    python34 tests don't run without python3-dev

    We cannot run py34 unit tests without python3-dev, but we
    also cannot add this to test-requirements.txt. The best we
    can do is add the issue to the devref/unit_tests.rst to help
    people find and fix the issue.
