I don't think so.  It seems to me that it should be one or the other.  If you are building a -native package then you don't need a native file and vice versa.

It could be but I didn't want to make unnecessary changes just to get llvm-native working.  I think few  people  even attempt to use a native-llvm for anything other than building llvm.  If anyone else needed this I would think that the  llvm-native recipe would have been updated by now by others.  In that regards this patch just not important.  I was just putting it out there as this tripped me up for a few hours before understanding what was happening.
