No - it's completely standalone, and should have no effect on things
that do not use Kconfiglib. The only changes besides adding the script
itself is to add two (well, three - there's one that's only used by
kconfigtest.py) targets to scripts/kconfig/Makefile that make it easier
to use the library by ensuring the environment is set up correctly.

You would only need to have Python installed if you are going to use
Kconfiglib directly (hard to get around with a Python library).
