Even if none of source code is updated, the following are every time rebuilt: CC arch/sh/boot/compressed/cache.o SHIPPED arch/sh/boot/compressed/ashiftrt.S AS arch/sh/boot/compressed/ashiftrt.o SHIPPED arch/sh/boot/compressed/ashldi3.c CC arch/sh/boot/compressed/ashldi3.o SHIPPED arch/sh/boot/compressed/ashrsi3.S AS arch/sh/boot/compressed/ashrsi3.o SHIPPED arch/sh/boot/compressed/ashlsi3.S AS arch/sh/boot/compressed/ashlsi3.o SHIPPED arch/sh/boot/compressed/lshrsi3.S AS arch/sh/boot/compressed/lshrsi3.o LD arch/sh/boot/compressed/vmlinux OBJCOPY arch/sh/boot/zImage Add build artifacts to 'targets' as needed. I turned the library files to check-in files. It is simpler than copying from arch/sh/lib/ at build-time.
