[PATCH 1/1] Allow building for ppc32 platforms.

[Tony Breeds]

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.
