I see two problems:
- this fixes sunxi and possibly leaves other platforms unfixed
- when the spl on sunxi grows some more, the bss won't fit and you'll
  have a problem again, except much bigger this time

I'd rather have this fixed on tiny-printf level with a bit of
documentation on why that's done the way it's done.
