This is needed to make it available to more packages, for caching
purposes.
For caching, the version itself may not be enough during development.
But for regular releases, the version provides some protection against
accidentally using a cache entry that is invalid in a newer version.
This is necessary to avoid a circular dependency in the loader (which
soon will need to read the Go version) and because it seems like a
better place anyway.
