    build,arm: Fix deps check of head.o
    
    arm*/head.o isn't in obj-y or extra-y, so make don't load the
    associated .*.d file (or .*.cmd file when if_changed will be used).
    There is a workaround where .*.d file is added manually into DEPS.
    
    Changing DEPS isn't needed, we can simply add head.o into extra-y and
    the dependency files will be loaded.
