I think the main problem with these articles is that the examples given are exceedingly simplistic, and hence in no way represent real world build systems. It's very easy to have a build system look nice and clean for trivial examples, when it breaks down is when the software it builds gets more complicated and the number of hacks and extra code is added making the build system into a big mess.
