Good point, its head of layer, actually the patch merged best from meta-virt
and oe-meta-go, meta-virt recipes were cleaner and using that as base I have
added the support for bbclassextend from oe-meta-go. I will amend the commit
message in a follow up

we could think of including govendor or some such tool ?

I dont think this patch uses destsuffix the way oe-meta-go did
but if you still have these issues please report.
