Hello, how about this RFC patch:

Subject: [RFC PATCH] distro_features_check.bbclass: skip for native and nativesdk

The distro features should have no effect to the native or nativesdk
recipe, for example, if we need build a tool for target based on
directfb, the native recipe should still be built based on x11 which is
more common on the host.
