When I built the RTEMS+GBA toolset, I also tried to build the RTEMS
+NDS ones as well. The tools did compile without complaints. When I
tried to compile a simple hello program, the compiler stated that the
NDS supported mixing Thumb and normal ARM code, but the run-time
system was not built to support it. Since I wanted to focus on GBA
first, I haven't bothered to rebuild the tools for NDS. If you follow
the instructions on  http://www.rtems.com/wiki/index.php/RTEMSAda
there's a good chance you can generate a usable set of tools. If you
run into problems, I'm sure someone from the RTEMS mailing list will
be happy to help out.

Btw, I read somewhere on the RTEMS mailing list that the NDS support
is now updated to use DevKitPro.
