+Make oasis-node binaries made with GoReleaser via GitHub Actions reproducible
+again.
+
+Add `-buildid=` back to `ldflags` to make builds reproducible again.
+
+As noted in [60641ce](
+https://github.com/oasislabs/oasis-core/commit/60641ce41a9c2402f1b539375e1dd4e0eb45272d),
+this should be no longer necessary with Go 1.13.4+, but there appears to be a
+[specific issue with GoReleaser's build handling](
+https://github.com/oasislabs/goreleaser/issues/1).

+github: Add ci-reproducibility workflow
+
+The workflow spawns two build jobs that use the same build environment, except
+for the path of the git checkout.
+The `oasis-node` binary is built two times, once directly via Make's `go build`
+invocation and the second time using the [GoReleaser](https://goreleaser.com/)
+tool that is used to make the official Oasis Core releases.
+The last workflow job compares both checksums of both builds and errors if they
+are not the same.
