That still doesn't fix it for any external defconfig. Adding a 'default
y' to BR2_LINUX_KERNEL_USE_INTREE_DTS will likewise break it for users
of BR2_LINUX_KERNEL_USE_CUSTOM_DTS. Perhaps we can change the logic to
look for nonempty BR2_LINUX_KERNEL_INTREE_DTS_NAME /
BR2_LINUX_KERNEL_CUSTOM_DTS_PATH variables?
