Same code. Use the generic version. The special Makefile treatment is
pointless anyway as init_task.o contains only data which is handled by
the linker script. So no point on being treated like head text.

Make the linker script align the task on THREAD_SIZE and not on
PAGE_SIZE, as PAGE_SIZE might be smaller than THREAD_SIZE.
