Debugging

Either the internal rpcs3 debugger is good enough, but one can also connect with gdb to rpcs3.
It does need a multiarch version of gdb, because unfortunately the one from the toolchain does not work as it seems.
Steps:

1. On RHEL gdb or Debian gdb-multiarch
2. set arch powerpc:common
3. target remote localhost:2345

Additional Notes:
Get current instruction adress: rdx + 0x474 (not confirmed)
