Ah! Ok. Back to square one I guess. Its currently observed in our downstream setups
only. I have no good reason to justify it. Reproducing this issue is gonna be difficult.
Let me see if I can monitor file changes and pinpoint the exact condition.
But this is going to take a while.

If it helps, the scenario is IMAGE_TYPE set to wic-img and targz-img is
inherited so both are executed for a build. Also, on a seperate note 
IMAGE_TYPE's functionality could be extended to provide multiple image types.
I believe we could specify only one right now. Former is more clean and particularly
useful if one wants a wic for sd boot and tar for nfsroot. Planning to take this up
next.
