Hi Petter,

Thanks for testing that out. That is indeed exactly what I was seeing
before I added the directory creation.

I did do the following test for both 3.18.x and 4.1.3 kernels (rpi2)

bitbake -f -c cleansstate virtual/kernel
bitbake -f virtual/kernel

I've just re-run that again here and it works for me as-is. I thought
cleansstate was causing me to build from scratch so I'm unclear as to
why I'm not seeing the problem...

NB. I'd also add that for preference I'd like to see the kernel build
Makefile patched with whatever is in 4.1 to create that needed overlays
directory but I've had a look and can't spot it.

Cheers,

Alex
