PPC is normally big endian but has special little endian load/store instructions. Using these avoids a separate byteswap. This makes the vorbis decoder about 5% faster. Not much else uses little-endian read/write extensively. GCC generates horrible PPC code for the default AV_[RW]B64 (which uses a packed struct), so we override it with a plain pointer cast.
