I haven't looked so you might already have it.

#if defined(__CELLOS_LV2__)
   identify big-endian PS3

This should handle both Synergistic Processing Unit( __SPU__ ) and 
Primary Processing Unit ( defined(__PU__) || defined(__PPU__) )

#if defined(R5900)
   little-endian PS2.

#if defined(HOLLYWOOD_REV) || defined(REVOLUTION)
   big-endian Wii

I'm not sure about WiiU.

#if defined(_XENON) || (_XBOX_VER == 200)
  big-endian ppc Xbox360
#else
  little-endian x86 Xbox

although this check won't necessarily hold once the new xbox comes out, 
IIRC original xbox is just _XBOX_VER < 200 and it's probably safe to 
assume _XBOX_VER > 200 will be the new xbox and just error out there so 
someone can set it up correctly when it's released.

You can also check defined(_XENON) && defined(_M_PPC) to see if you're 
building for xbox360.
