Okay, that makes good sense.  But that's the kind of thing the comment
at the top of tm-embed.h should explain.  This file isn't about the
tm-i386.h re-org --- it's about the fact that embedded targets are
distinct from the others.

I have no idea who needs to approve this, which I guess means Stan.  :)
I certainly approve of it.  Mark Salter and I could have used this
