The smaller fix in `constructLldCommand` would handle the profile runtime case, but it would still leave device-only code object linking on a separate path.

The other issue this patch is trying to fix is that device-only multi-arch links do not go through the packager/linker-wrapper pipeline today, so they also miss the normal `--offload-jobs` parallelization. This patch unifies that path, and the profile runtime case is one symptom of the same split.
