Expected Behavior

The testsuite demonstrate that this is possible in test/blackbox-tests/test-cases/promote/non-existent.t/run.t
My reproduction looks very similar to this test but fail with an error.

Actual Behavior

dune build @bench:

File "dune", line 3, characters 0-55:
3 | (rule
4 |  (alias bench)
5 |  (action
6 |   (diff promoted x.gen)))
Error: Unable to resolve symlink _build/default/promoted
