I was implictly thinking about ARM processors when I wrote the above because
they are the focus of my current projects.

Seeing that the OP was talking about the AVR, I should also point out that
I have successfully built a older version of the AVR Ada standalone cross
compiler in the past which worked ok within the limits of the port.

This is from memory, but there were additional AVR Ada specific steps
involved, including applying patches to the toolchain source (IIRC).

However, I don't remember it as been anything too difficult to work out
given that I had already been through a similar process getting Ada code
to work under RTEMS on a ARM board.
