Add configurations to makefile to run/open debugger automatically

With this makefile you can execute the compiled program in desmume automatically by typing make run and automatically debu by typing make gdb. Chances are the run configuration will work on the VM while the other functions probably are only useful for me. (specifically, make check requires cppcheck, which is very unlikely to be installed on the VM)

I guess in general this only useful for ppl like me doing things with the terminal
