When `--build-id` is specified, lld hashes the whole output file. A failure on macOS in the worst case can mean output non-determinism on macOS, but it is unclear how this can be the case. 278f80ce95401f7920845d1281aa99804a139b6c should not change build ID for the two tests.

I've debugged such build ID problems in the past, but I need to inspect the output files and compare them. Is it anyway to download the output file from that macOS machine?
