build system: move flag generation to Rakefile for several features
Features include debuging, profiling, optimizations & sanitizers. The flags don't depend on something that's actually tested, but only on which features are enabled and which compiler & compiler version is used. Therefore doing it in Ruby instead of sh is easier.
