If you link against libtracecmd you get a few extraneous warnings and printf's that aren't related to your tool. So by default make the path to the events you are tracing use pr_stat() so if it's not defined we don't get the output, and make the weak warning() do nothing by default. The trace-cmd stuff has this defined so it'll continue to work normally, it just won't be noisy for consumers of libtracecmd. Thanks,
