Ugh, yes. It's an optional circular dependency and an opaque side effect 
rolled in one.

I'd rather go with bbappends in meta-vala (even though having them means 
that oe-core has failed to serve the needs of meta-vala users), or just 
keep vala in oe-core - it's not big and doesn't have special needs.
