sh: fix build error for invisible CONFIG_BUILTIN_DTB_SOURCE
I fixed a similar build error in commit 1b1e4ee86e00 ("sh: fix build error for empty CONFIG_BUILTIN_DTB_SOURCE"), but it came back again. Since commit 37c8a5fafa3b ("kbuild: consolidate Devicetree dtb build rules"), the combination of CONFIG_OF_EARLY_FLATTREE=y and CONFIG_USE_BUILTIN_DTB=n results in the following build error: make[1]: *** No rule to make target 'arch/sh/boot/dts/.dtb.o', needed by 'arch/sh/boot/dts/built-in.a'. Stop. Prior to that commit, there was only one path to descend into arch/sh/boot/dts/, and arch/sh/Makefile correctly guards it with CONFIG_USE_BUILTIN_DTB: core-$(CONFIG_USE_BUILTIN_DTB) += arch/sh/boot/dts/ Now, there is another path to descend there from the top Makefile when CONFIG_OF_EARLY_FLATTREE=y. If CONFIG_USE_BUILTIN_DTB is disabled, CONFIG_BUILTIN_DTB_SOURCE is invisible instead of defined as "". Add obj-$(CONFIG_USE_BUILTIN_DTB) guard to avoid the attempt to build the non-existing file.
