Pff partially working. No PID. When setting the audio clock on the bbb to 44098 the master and slave clock keep diverging instead of converging ...

# This is a nasty kludge: we want to be able to optionally link in a default

# we want to link in the default main file or not. The kludge is the mess of a shell script
# line below. Surely there's a better way to do this?
