New OPTIONS structure - deselect all

[Paul Schmehl]

I'm working on updating the barnyard2 port, and I'm changing the port to 
use the new OPTIONS structure.  It seems no matter what I do, the first 
port OPTION is automatically selected.

I've tried OPTIONS_DEFAULT=, OPTIONS_DEFAULT= none, and not using 
OPTIONS_DEFAULT at all.  I do not want the first OPTION selected.  I want 
them all deselected so the person installing can choose the appropriate 
ones for their situation.

What's the secret sauce for this?  I've looked through bsd.options.mk, but 
I can't see it.
