(trunk) #3949 "Add --enable-lightweight argument to configure" -- fixed.

TR_EMBEDDED has been around for awhile, but few (any?) repackagers are aware of it. If it was "advertised" through a configure-time argument, and in the status messages at the end of the configure script, more repackagers would be aware of it.
