[PATCH] devupstream: Allow support of native class extensions

From: Richard Purdie <hidden>
Date: 2021-08-04 13:10:51
Subsystem: the rest · Maintainer: Linus Torvalds

It is useful to be able to use the class with recipes using BBCLASSEXTEND
for native extensions. This adds the magic required to do that.
