head.o is been built twice, once because it is in $(ALL_OBJS) and a

Fix this by adding a dependency of "head.o" on the directory
"arch/arm/".
Also, we should avoid building object that are in subdirectories, so
move the declaration in there. This doesn't change anything as
"arch/arm/built_in.o" depends on "arch/arm/$subarch/built_in.o" which
depends on $(extra-y), so we still need to depend on
"arch/arm/built_in.o".
head.o as to be right at the beginning of the binary. Will this still be
guaranteed with this change?
I guess what you want to know is: no change to the final binary.
The layout of the final binary is defined by $(ALL_OBJS), which this
patch doesn't change.
This patch only ask make that when it want to build "head.o", it need
first to build "arm/built_in.o", then "head.o" exist so we ask make to
not do anything in this Makefile.
Cool. Thanks for the confirmation! You can add:
