SERIAL_CONSOLES is typically set differently for different machines. But
busybox is not machine-specific, therefore using SERIAL_CONSOLE like
this prevents sstate/package reuse or worse, causes package versioning
problems.

This probably was not noticed by the auto-testers because it only causes
tests to fail when SERIAL_CONSOLES is really set differently. I'm
wondering whether there should be variable flag for machine-specific
variables: then using such variables in machine-independent recipes
could trigger a QA warning.
