    After you clean up the aforementioned build configs:
    - If you still have build configs, use:
        . ${ROOT_DIR}/${KERNEL_DIR}/build.config.constants
      at the top of your build config, and file a bug with your existing build config.
    - If you do not have any build configs, delete kernel_build.build_config entirely.
