I like this idea much better than the first one.

Tested and it doesn't work. With the --with-gameuser=":gamestat"
configure option, it properly installs the update-game-score binary.
In spite of this, Emacs doesn't use the shared directory, but creates
a score file in the user's home directory instead.

The reason is that gameuser and gamegroup are not propagated to the
top-level Makefile:
