The answer is that a failure looks like this:

duplicate symbol _FeBeWaitSet in:   access/common/printtup.o   access/transam/parallel.o
duplicate symbol _FeBeWaitSet in:   access/common/printtup.o   commands/async.o
duplicate symbol _FeBeWaitSet in:   access/common/printtup.o   commands/copy.o
duplicate symbol _FeBeWaitSet in:   access/common/printtup.o   libpq/be-secure.o
duplicate symbol _FeBeWaitSet in:   access/common/printtup.o   libpq/auth.o
duplicate symbol _FeBeWaitSet in:   access/common/printtup.o   libpq/hba.o
duplicate symbol _FeBeWaitSet in:   access/common/printtup.o   libpq/pqcomm.o
... etc etc ...
