this means that ENDIAN_FORCE is obsolite since it's always overwritten with PREPROCESSOR
Since the preprocessor should never be able to pick wrong, it's easier this way
specially when compiling universal binaries as they got both endianess
it needs both PPC and x86 libs to compile
due to this fact, compilation with libPNG or SDL is not tested (dedicated servers only)
only PPC part is tested as I don't have x86 OSX
