I thought about this approach too. I didn't use it because of the
following reasons.
1) IMHO, we haven't reached a point that a separate libuuid recipe
becomes a necessity.
Splitting a recipe may need more compelling reasons.
2) If we are really going to do so, I think we may need an RFC in other
patches. I don't want to make a patchset regarding package upgrades
involve too many changes.
