PowerPC always re-builds DTB even if nothing has been changed. As for other architectures, arch/*/boot/dts/Makefile builds DTB by using the dtb-y syntax. In contrast, arch/powerpc/boot/dts/(fsl/)Makefile does nothing unless CONFIG_OF_ALL_DTBS is defined. Instead, arch/powerpc/boot/Makefile builds DTB on demand. You need to add DTB to 'targets' explicitly so .*.cmd files are included.
