Currently any ppc32 compile will error out with "Please, fix this for
your platform". While this is a great way to encourage people to update
the code it seesm to be a disinsentive for distros to package
kexec-tools for powerpc (incl. 64-bit).
Make get_memory_ranges() do the right thing in the GameCube case and
fail at runtime for all other ppc32 cases.
