[Boost-build] How to set "USER_OPTIONS" in user-config.jam to pass to darwin.jam

How do I go about setting something either on the command line or in  
the user-config.jam file in order to set the "USER_OPTIONS" setting?

I tried the obvious:

USER_OPTIONS = " -headerpad_max_install_names " ;

and then in darwin.jam I have the following:

ECHO USER_OPTIONS are $(USER_OPTIONS) ;

but I get an empty string.

Thanks for any help on this.
