I didn't know that rpm-native was built in any case, rpm being selected as 
package manager or not.

Indeed, this can lead to undefined behavior. I can propose some solutions but 
which one would you find better :
	- Setting a weak assignment for rpmlibdir inside rpm recipe
	- Setting a default assignment for rpmlibdir_class-native inside rpm recipe
	- Another option I didn't think of
