Understood. it is extremely useful for people getting started with rtems on
the BeagleBone though! On my Ubuntu 18.04 host the system dtc was version
1.4.5 which also didn't support the -@ option, so I took Vijays advice and
downloaded and built 1.6.0 which solved the problem.

That must be my mistake. I was sure I read that the other night but can't
find the website or thread I was reading now so it was probably either bad
information or my misinterpretation - apologies for that.

Thanks for this. I thought my rtems-libbsd repo was up to date, but I did
a git pull --recurse-submodules and now make libbsd succeeds.
Loading the hello world test app onto the board produces the expected
output in a terminal session, so I think I am now in a position to make a
start on the eQEP driver.

Many thanks for your help!
