Duncan, this patch gets llvm-gcc to build, but it still doesn't  
answer the big question: why does TargetData contain information  
about the host?  I don't think this is the right approach.  Also, you  
can get the host endianness without autoconf by using something  
simple like:

bool islittleendian() {
   union {
     int i;
     char c;
   };

   i = 1;
   return c;
}
