This variable was last used in code removed way back in
45781adb9a ("get_remote_url(): use the same data source as ls-remote
to get remote urls", 2011-03-01).
Since it's only used in git-submodule.sh it could have been the case
that the code there relied on us setting $GIT_DIR, but that's not the
case. The only use of $GIT_DIR in git-submodule.sh involves a $GIT_DIR
variable that the code there sets by itself.
