The trouble is as others have mentioned, COMPATIBLE_MACHINE has always worked this way. We can't really change that without a wider discussion and at this point in the release in particular, I can't take such a patch. We do really need to think about the behaviour as it does do unexpected things and catch people out. I'd suggest you add a '$' to the end of the regex in linux-yocto-tiny to resolve this. We could also add '$' to the end of the other usages and make it clear it is a regex?
