Ensure .dyn_hi doesn't overwrite .hi
This commit fixes the following bug: when `outputHi` is set, and
both `.dyn_hi` and `.hi` are needed, both would be written to
`outputHi`, causing `.dyn_hi` to overwrite `.hi`. This causes
subsequent `readIface` to fail - "mismatched interface file profile
tag (wanted "", got "dyn")" - triggering unnecessary rebuild.
