This doesn't quite follow. "target", "nativesdk" and "native" are all
different separate filesystems and not connected. Yes, you can use
usrmerge on some (or all?) of them but you don't have to have them
match.

Forcing them to match is likely just working around an underlying issue
which needs to be fixed.

What were the real failures?

For example, this would stop native or nativesdk sstate being reused
between differently configured builds when it could be.

Cheers,
