I'd suggest adding some "bogus" things to your machine-extra.conf,
because I don't think the file will actually be used (or even parsed)
anywhere.

You can override SERIAL_CONSOLES in your DISTRO config, as that takes
precedence over the machine config. In local.conf it won't work because
the MACHINE config is included after it.

Another approach is to grep on which recipes use it (half a dozen) and
then create a bbappend for each. That's the approach I've used recently.
