That's certainly a better thing. It would be better yet to figure out
why BUG() didn't do it automatically.

Without CONFIG_BUG, it looks like powerpc picks up

  #ifndef HAVE_ARCH_BUG
  #define BUG() do {} while (1)

which should still make it pointless to have the return.  But I might
have missed something.
