I have both of the issues fixed, but am waiting for a build cycle to
complete.

Fundamentally nothing needs to mess with the kernel source for out of
tree builds anymore, so just testing for 'build' to exist and trusting
that it is right is the proper thing to do.

I tweaked both this and the build-appliance image to do just that.

If you want, I can send the patch before my builds complete (since
it will be tomorrow before they are done).
