[PATCH] Don't always ask about Intel RNGs

 Hello.  The following patch hides the option for Intel (i8x0) RNG
 support when it's not a useful option.  This is based off of a patch
 That was accepted in 2.4.19-pre6.  While I suspect this is an ia32-only
 option, it is possible that it's used on ia64 as well, so we test for
 both before offering Intel i8x0 RNG support.
