The difference between "always" and "extra-y" is that the targets listed in $(always) are always built, whereas the ones in $(extra-y) are built only when KBUILD_BUILTIN is set. So, "make modules" does not build the targets in $(extra-y). vmlinux.lds is only needed for linking vmlinux. So, adding it to extra-y is more correct. In fact, arch/x86/kernel/Makefile does this. Fix the example code.
