PowerPC "supports" both, but I believe it's typically run in big endian mode. Same with MIPS AFAIK.
(Mini rant: CPU people seem to think that you can avoid endianness issues by just supporting both little and big endian, not realizing the mess they're creating higher up the stack. The OS's ABI needs to be either big endian or little endian. Switchable endianness at runtime solves nothing and causes a horrendous mess.)
