Subject: runqemu-internal: Fixes unary operator expected in new TCPSERIAL_PORTNUM
X-Git-Tag: 2015-10~706

runqemu-internal: Fixes unary operator expected in new TCPSERIAL_PORTNUM

If $TCPSERIAL_PORTNUM is empty string causes an error because
expands the expresion to,

$TCPSERIAL_PORTNUM == "" -> == ""
