build status for cross builds?

Cross build statistics will be great, especially since 3.0 was so broken
for many embedded targets.

I doubt that you have any cross build reports on your existing list,
though I might be wrong.  One issue about cross builds is that just
getting a cross compiler to build isn't as strong an indication of success
as getting a native compiler to pass a 3-stage bootstrap; at least we know
in the latter case that gcc can build gcc.  (OK, it will build a library).

Unfortunately no, as many possible triples mean the same thing but
config.guess will only choose one of them.  Just the same you could
just publish what the users send you.

I'll defer to the embedded gcc experts.  Mike Stump, Joel Sherill, what do
you think?
