No, both are defined for both.
On PPC, I get
TARGET_RT_BIG_ENDIAN = 1
TARGET_RT_LITTLE_ENDIAN = 0
So #ifdef wouldn't work, for example
#ifdef TARGET_RT_BIG_ENDIAN
big_endian_code();
#else
little_endian_code();
#endif
would run big_endian_code() even on little-endian platforms.
Hope that makes sense.
