AFAICS, `make test-prebuilt` does not report a non-zero exit code on failure, and the external script looks for `build/run-test-prebuilt/make-support/exit-with-error` to check for error. But it does not _set_ the exit code on its own when the failure is discovered, neither it sets `failure=true` on generic failure.

I thought about reporting non-zero exit code from the parsing script, but it does not feel clean to return non-zero exit code from the _parsing script_. Non-zero exit code from that script should signify the error in the script itself.
