* distrooverrides.bbclass: DISTRO_FEATURES as overridesPatrick Ohly2017-06-141-0/+32
This achieves the same goal as the same change to bitbake.conf itself, but because the class gets added later as part expanding INHERIT, this new approach is less likely to run into problems when DISTRO_FEATURES contains complex code. Another difference is that the class currently does not get inherited by default and thus is completely absent from a build unless some layer or include file adds it to INHERIT. Compared to the earlier code in bitbake.conf and a similar class in intel-iot-refkit, additional overrides now get sorted. This makes the final OVERRIDES more deterministic. The lessons learned about unintentionally depending on OVERRIDES are documented in the class because such problems are more likely to show up as unexpected signature differences when using this class.
