Hmm, I'm not quite happy with this one. I get tons of warnings since 
REGISTER_TARGET_PRAGMAS is defined twice here on darwin. Once in 
darwin.h and once in rs6000.h. How is this longcall meant to work with 
darwin?
Should we check in rs6000.h for
if !defined REGISTER_TARGET_PRAGMAS
define REGISTER_TARGET_PRAGMAS
fi
And add the longcall pragma to darwin.h?
