[PATCH] implement AT_PLATFORM for powerpc

[Kumar Gala]

Paul,

This reminds me do we have a bit for having/not having the load/store  
string instructions. If memory serves me there were some discussions  
of looking at "depreciating" the instructions from the architecture.  
Freescale Book-E implementations already do NOT implement them. I  
doubt that Freescale will over implement these instructions ever again.
