I've had the problem with 'dummy.o' in the past. IMO
a better solution should be found because - especially
for the 'user' as opposed to a 'developer' - it is hard
to understand and find the cause of the problem.

You miss to define something and it gets pulled in from
'dummy.o' which then causes linker errors due to
multiply defined stuff when in fact an error should report
the missing item - not exactly user-friendly behavior...

FWIW
