Automatically choose some interface combinations

on factory default boot.
This allows the system to switch interfaces from the newer ones in the
default config (e.g. em0 em1) back to the interfaces used by:
Alix - vr1 vr0
APU - re1 re2
that match the WAN and LAN labels printed on many existing devices.
It means these devices can boot the default config and this will
automatically detect that there is no em0/em1 and will instead select
whatever exists out of vr1/vr0 or re1/re2. This avoids the user having
to use the serial cable to do interface assignment when starting a brand
new image, or when resetting to factory defaults. It could easily be
extended to other common interface combinations.
For me, this (or similar) would be very beneficial. At remote sites it
is really good if it is possible to do reset to factory defaults, or put
a fresh CF/SD card in, and the system boots without needing to connect a
serial cable and do interface assignment.
