Hi Bruce,
I've been able to reproduce the problem in a more minimal environment.

To build a basic Yocto Raspberry Pi environment I based my build on the instructions found here:
https://themeaningfulengineer.github.io/exploring-yocto-with-raspberrypi/

The steps that I actually executed are:

git clone -b morty --single-branch git://git.yoctoproject.org/poky
cd poky/
git clone -b morty http://git.yoctoproject.org/git/meta-raspberrypi
source oe-init-build-env rpi-build

In rpi-build/conf/local.conf I changed the MACHINE assignment to "raspberrypi2" from "qemu86"

In rpi-build/conf/bblayers.conf I added "  /home/gwilson/Qt/poky/meta-raspberrypi \" to pick up the raspberry layer.

At this point I ran:
bitbake rpi-hwup-image

to verify that the environment was correct. The build finished with only a couple of warnings about checksum problems and using alternate mirrors.
I then copied in my kernel scripts and added in the directory to the bblayers file. 
When I rebuilt with these changes I get the same warnings/errors about changing the kernel config that I get with my full build environment.
I've attached my meta-test directory with the kernel configuration .bbappend and .scc & .cfg files, and the final bblayers.conf & local.conf files.
Thank you for taking a look at this.
Regards,
Greg Wilson-Lindberg
