To enable future analysis of the dependency links between components, log the dependencies of each DPDK component as it gets processed. This could potentially allow other tools to automatically enable or disable components based on the desired end components to be built, e.g. if the user requests net/ice, ensure that common/iavf is also enabled in the drivers. The output file produced is in "dot" or "graphviz" format, which allows producing a graphical representation of the DPDK dependency tree if so desired. For example: "dot -Tpng -O build/deps.dot" to produce the image file "build/deps.dot.png".
