Make build without `games'

[Joel Dinel <dinjo@touchtunes.com>]

I'm trying to figure out how to run a 'make build' and specify things I
do not want to be built. I read the FAQ, no luck there. I've looked at
bsd.sys.mk and sys.mk, but I am uncertain that the answer's in there.

Basically, I installed a 3.0 box with everything except XFree and the
games. I'm fetching the patch branch as we speak, and should launch a
'make build' soon. I'd just like to avoid building the games from
source.

A courtesy CC would be greatly appreciated :)

Thanks to all!
