hmmm SERIAL_CONSOLE is the place where it should be set and then
shadow uses that to generate securetty etc. right now SERIAL_CONSOLE
is a machine property set in machine.conf files. So may be we can let it
emit both for omaps ? may be that will work otherwise we have to override it
in recipes which can be ugly.
