We're going to have to talk to the guys who decided to build the Ada
runtime without debugging info. The normal way to build the runtime
is no debug info *except* for a few files. This is really doing a
disservice to the users!

Grumble, grumble, grumble. Sorry.

It's actuall there, see ada-lang.c:ada_exception_sal. But upon more
careful inspection, I think it might have become dead code:
The error is only raised if we failed to look that symbol up, but
the call to ada_exception_support_info_sniffer to have already errored
out if that was the case. So I think we can replace that by an assertion
and simplify the testcase.

That's going to be on me, but I won't have much time this week.

In the meantime...

I'll try to think of a better error message - it's not my forte...

... I think that this is a good stop-gap measure. It helps you, so
it's OK to go in. I'll cleanup afterwards anyways.  Thanks for doing
that.
