The problem case Leon and I are seeing:

  Multiple kernel recipes are getting built when doing 'bitbake 
something', which makes builds fail, or worse, succeed and you end up 
with bogus kernels for your machine.

In the past we have worked around it by adding COMPATIBLE_MACHINE to 
each kernel (people should do that, yes, I'm looking at you, 
linux-bd-neon). But now we have linux_<version>.bb that are meant to be 
reused, we are stuck with this 'feature' again.

Maybe we should special case recipes that do 'inherit kernel'?
