Is binary npm module rebuilding if build/prod are the same?

I’m (still) using meteor-up 0.9.7. It rebuilds binary npm modules. If the server running the mup-deployed Meteor apps is the same architecture (linux x86_64) as the server running meteor build (and both build server and prod server use Node.js 0.10.x), do I still need to be rebuilding the binary npm modules?

I’m thinking not based on https://github.com/arunoda/meteor-up/tree/mupx#migrating-from-meteor-up-0x.
