I don't think QEmu supports leon2 already.

The Couverture project added support for leon2 in a separate patch,  
but I don't think it is merged to trunk
see http://forge.open-do.org/projects/couverture/

patch is there http://forge.open-do.org/scm/viewvc.php/trunk/couverture/tools/?root=couverture
(note the patch adds at697 as a machine for QEmu. It is for the Atmel  
AT697 board, based on a leon2 chip see
	http://www.atmel.com/dyn/products/product_card.asp?part_id=3178)
I could get an application running with it with the following line:

./qemu-system-sparc -nographic -M at697 -kernel <my_app>
I could get one application running using a gnat compiler for leon,  
but not using RTEMS 4.8 :(
Perhaps the patch mentioned below will provide some guidance.
Note that couverture also has an example with a bareboard ppc and a  
bareboard leon (no kernel at all, not even the gnat runtime)
perhaps this will provide an entrypoint. (in the tools/xcov/examples  
directory)
Hope this helps
Note I work on the Couverture project, but I'm not directly involved  
in the qemu part of this project.
