[U-Boot-Users] Testing a cross compiler for a mpc8540 cpu

Does anyone know a good way to test to see if a cross compiler is working? I have what I believe to be a cross compiler for a mpc8540 cpu. However I am not sure if its working. I can compile u-boot with the compiler but that does not tell me much since u-boot does not support the board I am using specifically. I really don't want to go forward working on getting u-boot to run on this board only to find out of compiler is broken. Anyone have any ideas?

Thanks
