Isn't it, that you have a difficult to maintain build approach if you 
supply multiple -I anyway? If we can, we should simply avoid it.

If we have a perfect build system, all switches etc. would be reflected 
in a way, that would lead to a re-build.

Meanwhile we may want to avoid this pitfall by simply having one 
location for a particular link option and to make the target dependent 
on this file.
