In the patch introducing the test-case, it was mentioned:
...
The dwarf assembly test-case mimics the scenario described above, and
reproduces the FAIL with and without -readnow, for both mentioned OS
configurations.
...

Already before this commit, that no longer seems to be the case: when
reverting the fix, the test-case only fails with target board readnow.

Anyway, I've confirmed that after this commit, reverting the fix still
make the test-case fail with target board readnow.

Thanks,
