I was just asking a similar question on the gcc list, see this thread here:
<http://gcc.gnu.org/ml/gcc/2004-12/msg00585.html>

You'll probably have to ask the simulavr people for more information, or 
ask them to make the changes needed.

Alternatively, there is Avrora:
<http://compilers.cs.ucla.edu/avrora/>
Which has just been released and says it can be used as a GDB backend.

I'm very intereted in how you got the testsuite working, even if 
partially. Do you have something written (a how-to) about it?

Getting the GCC testuite running on the AVR is very badly needed work, 
and your efforts are very appreciated!
