(svn r3264) -Codechange: [OSX] OSX targets will now always use the preprocessor to determine endianess
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
