rs6000: Fix AIX aggregate passing fix

Browse Source 
David's fix for the AIX aggregate passing from yesterday unfortunately
also triggers on powerpc64-linux.  This fixes it.


	* config/rs6000/rs6000.c (rs6000_function_arg): Only do the special
	aggregate handling on actual AIX, not on somewhat similar systems.
	(rs6000_arg_partial_bytes): Ditto.
