Hello!
I recently had a situation where I needed to set file capabilities for a binary in an image. For my build I solved it via pkg_postinst and an adaption of the libcap-native PACKAGECONFIG at distro level (credits to: https://stackoverflow.com/a/43637771).

I saw that the gnome-keyring recipe (meta-openembedded layer) has a problem doing this and reverts back to pkg_postinst_ontarget. A fix would be changing the PACKAGECONFIG for libcap-native (openembedded-core layer) to include "attr". 

Before submitting interdependent patches to multiple mailinglists I wanted to ask here for opinions wether it is sensible to change the libcap-native PACKAGECONFIG for this.
