The default mache model for qemu-system-ppc is g3beige. You can't plug an e500 
core into a Mac based system. Instead, you want to run a different machine 
type, like ppce500 or mpc8544ds by defining it through -M.

These machine models don't support running firmware yet, so you have to 
manually specify your Linux kernel on the command line with -kernel. You 
usually also don't find graphics on these SoCs, so I'd recommend to run QEMU in 
serial port output mode using -nographic. That gives you a command line like 
this:

  $ qemu-system-ppc -M ppce500 -nographic -kernel uImage

The ppce500 machine already defaults to e500v2, so no need to specify it on the 
command line. Please make sure to enable support for the QEMU machine in your 
guest kernel config to enable support for the ppce500 machine 
(CONFIG_PPC_QEMU_E500).
