Is it possible to do something along the lines of PACKAGE_CONFIG in the linux-yocto.bbappend? For example, in the libvirt package one can use PACKAGE_CONFIG to construct a "minimal" build of libvirt. What would be the method for one to do the same in this package?<br>

Yes, I imagine that worst case there can be a SRC_URI_distro definition that includes only the .scc files required for that "minimal" image build, but it seems like we want to keep away from that as much as possible being that this isn't a distro layer.<br>
