Hi Paul.

True. It was a false statement. The reason behind why I thought it
picked up the wrong recipe was due to other reasons.
I now see that it seems to pick up the 4.8 version in oe-core.

I see. Funny though that this was not seen on Yocto 1.4? But it
probably has a good explanation too.
The most important thing is that we can now conclude that it is safe
to ignore it. I guess it might have something to do with providing
references to ${SDKPATH} in EXTRA_OECONF_PATHS. But it is most likely
not worth the effort trying to fix it.
