I think the distinction is that if you use armv7at-neon, you *can* build
specific packages with thumb. Mostly, I guess, I don't think it makes sense
to use a tuning that specifically states that it can't run thumb code for
processors which can. Although... May not be an important distinction, really,
as you note.

Huh, that's an interesting point. I'll wave this at people and see what they
think of it.
