Still fails: https://buildd.debian.org/status/package.php?p=node-srs&suite=sid

Our baseline is z10, and z196 is newer. So if upstream now requires z196, we
have three options:

- Revert / fix that so upstream works with z10 again
- Remove nodejs from s390x
- Bump our baseline

See go and rustc for similar problems.
