You have a valid problem here however I really don't like the "arms
race" of making everything an append as the base definitions are
problematic. It would be this recipe today but a quick search shows
many other recipes which will have similar problems.
I think I'd prefer to see if we can drop the assignments in
native/nativesdk bbclass and improve things that way even if it is a
bit more invasive.
I'm testing a patch on master-next to test this and see how bad the
fallout is.
Cheers,
Richard
