qemu-system-ppc64 does not work on powerpc/qoriq_e6500_64

[Richi Dubey]

 ~/quick-start/rtems/6/bin/qemu-system-ppc64 -net none -nographic -M
ppce500 -m 1024M -kernel
~/quick-start/src/rtems/build/powerpc/qoriq_e6500_64/testsuites/smptests/smpschededf04.exe
-smp 4 -s -S

This is similar to the command I use to debug arm/realview_pbx_a9_qemu all
the time
