Using `sdist in sys.argv` works but not in general. scipy.distutils 
supports a general solution that in addition to the above problem, it 
can handle cases where configuration depends also on a platform (e.g. 
creating distributions on different platfrom from where it will be used).
So, I wouldn't use `sdist in sys.argv` but methods provided by 
scipy.distutils. For example, using depends keyword argument to 
Configuration.add_extension method, or functions that can filter out 
unnecessary sources, etc. If you have already used `sdist in sys.argv`, 
that's ok, just I may replace this approach with another one.
