As of today default .dtb will be built (and subsequently will be built-in kernel binary) even if CONFIG_ARC_BUILTIN_DTB_NAME is not set. But it is possible we're going to use external .dtb and so we don't want to have .dtb built-in kernel binary. For example that could be the case with: a) U-Boot which loads .dtb in DDR and passes its address to the kernel b) OpenWRT which embeds .dtb in existing kernel binary This change excludes .dtb building if CONFIG_ARC_BUILTIN_DTB_NAME is blank.
