First, note that this option is passed by SVN HEAD version of Boost.Build already.
Second, USER_OPTIONS is a variable internal to darwin.jam and/or gcc.jam, if you
try to poke at it, nothing good will happen.
Finally, you can use the following:

  project user-config : requirements <linkerflags>"-headerpad_max_install_names" ;

in user-config.jam
