The output of this is saved off as part of the autobuilder test result
output, e.g.:

https://autobuilder.yocto.io/pub/non-release/20190306-14/testresults/oe-selftest/pylint.log

If anyone has some time and wants to help out cleaning things up to get
better results, this would be a great and comparatively low learning
curve way to get started with helping with the project!

Right now we save errors only, ultimately we may be able to clean up
warnings too.

Cheers,

Richard
