If it's optional extra stuff like git shortcuts, then removing it from the 
makefiles and putting it in tools makes sense.  If it's mandatory stuff like 
OS detection, then it needs to stay where it is.

What's the actual problem you're trying to solve with this?  IMO duplication 
is less of a problem than overcomplicating the makefiles.
