# use whichever it finds first :-(

# The most straightforward way to make sure this doesn't happen is to delete
# the Contiki library. But it would be undesirable to do that on every build
# so the existence of the "wrong" object file is used to detect a switch and
# trigger deletion of the Contiki library - and the trigger file of course.
