I ran into this issue again after wiping my build directory.
I suspect it may be the kernel version checking logic causing the issue.

For a clean build directory:
$ bitbake -e core-image-minimal | grep ^RPI_KERNEL_VERSION
RPI_KERNEL_VERSION="None"

For a used build directory:
$ bitbake -e core-image-minimal | grep ^RPI_KERNEL_VERSION
RPI_KERNEL_VERSION="4.4.16"
