I believe $(LN_S) would be normal, though (a) I don't see it being used 
anywhere, despite the definition, and (b) while the GNU Coding Standards 
still say "If you use symbolic links, you should implement a fallback for 
systems that don't have symbolic links." I'm doubtful that's of practical 
relevance to systems people are building GCC on any more.

I don't have any comments on the other parts of this patch.
