I took this route and everything went well, and we can now build
‘bootstrap-tarballs’ on x86_64-linux.  I ended up doing additional

  e2690a8eb2 gnu: mes-rb5: Remove.
  da32015db0 gnu: mes-minimal-stripped: Explicitly disallow references.
  5510e1c483 gnu: mes: Remove 0.19.
  81096caf7d gnu: mes: Switch to Guile 3.0.
  114a9f1f80 gnu: mescc-tools: Update to 1.2.0.
  0b9da8b5a2 gnu: m2-planet: Update to 1.8.0.
  8b627a7701 gnu: mes-minimal: Remove unused variable.

Removing ‘mes-rb5’ was a bit disheartening but I guess it’d have to be
updated to the current tool versions.

I removed Mes 0.19 because it failed to build with Guile 3.0 and didn’t
appear to be needed any longer.

Let me know if you think I did anything wrong!
