    util: Provide no-op body for empty debug macros
    
    In the case where debug macros are disabled, we provide a no-op body.
    This allows you to do things like
    
    if (condition)
        gjs_debug_something("message");
    
    without the compiler thinking you are doing this
    
    if (condition);
    
    which it would flag as a warning.
