Google has open sourced a build tool called Bazel. It is early on and it may not work with bird. It would be great if the invocation of this build system would be "bazel build bird". I don't know if it is possible or practical at this time. I am used to "Make" too but I am always on the lookout for new and improved ways of doing things. I find that it is hard to improve on whatever has been proven to work. However, there is a tool called ONOS (Open Network Operating System) that uses bazel. The network remains the only part that doesn't benefit from virtualization. With a Network Operating System...?
