Some news: I got fairly quickly the Ada cross-compiler running based on
the work you did Nick. I didn't see the reported assembler problem so this
might have been fixed in the meanwhile (even in the 4.1.1 version).
However I'm unable to run the Ada testqueue, not sure what I'm doing wrong
but it looks like this does not support testing a built cross-compiler
running on the build machine itself.
With more difficulty I got the native Ada compiler built but it can't find
its run-time code and my limited Ada knowledge or GNAT experience
holds me a bit from seeing what's missing.

I won't have time to continue this for the next week, I'll check in what
I have done so far, maybe someone else wants to have a go. I'm more or
less sure it is fairly trivial to fix this but the Ada world is very
unknown to me...
