I think you should also remove the "manual" declarations from the .c
files that call the function, in this case fork_init() in  init/main.c;
otherwise there's no guarantee that those translation units actually
include the header that contain the proper declaration.

arch_release_thread_stack can probably just be removed completely after
the recent arch cleanup, since bb9d81264 (arch: remove tile port) no
arch seems to implement it.
