distro_features_check.bbclass: Allow checking of required/conflicting features
This add support to list required/confliting distro features for a recipe; this avoids user mistake when building recipes/images which would not work depending on DISTRO_FEATURES option set. Adding: ,----[ Use example ] | inherit distro_features_check | | REQUIRED_DISTRO_FEATURES = "x11" | CONFLICT_DISTRO_FEATURES_mx6 = "wayland" `---- In the image recipe allow us to make clear to user that this image needs X11 and /cannot/ be build with Wayland support in i.MX6 platforms, for example.
