Drop 'inline' from all the *_mod_init_arch() functions so that the compiler will warn about any bugs where they are unused due to not being wired up properly. (There are no such bugs currently, so this just establishes a more robust convention for the future. Of course, these functions also tend to get inlined anyway, regardless of the keyword.)
