No big deal I guess.

libsanitizer always puts
-lpthread -ldl -lm
into libsanitizer.spec, so I'd say it should be safe and you shouldn't even
need -ldl in dg-additional-options, as merely linking with -fsanitize=thread
should link -ldl in.

I think better to name it tsan_barrier.h or otherwise make it
clear what this is for.

And, I'd add unsigned count argument here, and pass it through
pthread_barrier_init, just in case you need more than 2 threads
in some test.
Also, what do you need <sched.h> for?
