Thanks.

I think it would be simpler to either:

* Have this set the python exception and not call error, or
* Likewise but just have it be done in arch_object_to_gdbarch.

With the current approach you have to have a try/catch and then throw an
exception; but really all you want is to set the python exception --
which is cheaper to do directly.

It would be handy to get this hunk in sooner.
It's obvious fwiw.
