Currently, for every ARC kernel build I see the following:
--------------->8-----------------
DTB arch/arc/boot/dts/angel4.dtb.S
AS arch/arc/boot/dts/angel4.dtb.o
LD arch/arc/boot/dts/built-in.o
rm arch/arc/boot/dts/angel4.dtb.S <-- forces rebuild next iter
CHK kernel/config_data.h
--------------->8-----------------
