This patch to add the oeqa.utils.readconfig module should really be
applied before all of the changes which make use it. It's a relatively
minor niggle, but this should really be 1/20.

This seems like it would be simpler with os.path.splitext()[1] ?

Since Python 3.2 that's just ConfigParser()[2]. As we require Python
3.4 or newer for BitBake you can just use configparser.ConfigParser()
here.
