	What is the correct command line syntax for "defining" a
variable to the Makefile?

	The expect port will make either with or without X11 support.
I want it without X11 and there is an ifdefine WITHOUT_X11 test in the
Makefile.  My only problem is I remember that it can be done, but I
don't remember the exact syntax.  Sometimes, if you get those wrong,
make still works but you get the build you didn't want.   Thank you.
