[OE-core] does busybox 1.19 still support the arg `-m'?

[Ni Qingliang]

in file meta/recipes-core/busybox/files/syslog
I found code section:
	if [ -n "$MARKINT" ]; then
		SYSLOG_ARGS="$SYSLOG_ARGS -m $MARKINT"
	fi
but I can't find `-m' in the help of syslogd.


syslogd --help                                                    
BusyBox v1.19.3 (2012-01-11 12:34:06 CST) multi-call binary.
