The use case is building a gpl3-free image, without having
to rely on outdated recipes from meta-gplv2 layer.

+Subject: [PATCH] setup.py: do not report missing dependencies for disabled
+ modules
+
+Reporting those missing dependencies is misleading as the modules would not
+have been built anyway. This particularly matters in oe-core's automated
+build completeness checker which relies on the report.
