Makefile: add GNU global tags support
GNU Global is another tags engine which is more like cscope in being
able to support finding both references and definitions. You will be
un-surprised to know it also integrates well with Emacs.
The main benefit of integrating it into find-src-path is it takes less
time to rebuild the database from scratch when you have a lot of build
directories under your source tree.
