_log/_vlog were always called so we always had a function call hit even if we're not debugging. Expand on the debugging macros so the decision to call _log/_vlog is done in the caller already. Also, make a log level difference between syscall_printf and system_printf. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
