No, it's a feature and a security one at that.  Exposing allot of
environment variables through sshd is a security hole.  To plug it, only
the minimum environment needed is provided.  You can add to that with
external scripts of your own.

I'd recommend a separate script that you can run after you login by
some convenient means of your own choosing.  This keeps it from
cluttering up your .bashrc file.  But that's just a suggestion.
