bjam link=static runtime-link=static

Would probably do that (which is to say pass -static to the compiler).

Otherwise:

bjam cxxflags=-static

Lets you inject arbitrary compiler flags.

But it sounds to me like program_options might need patching for this 
platform?  If so please file a Trac ticket at svn.boost.org and set the 
component to "program_options".

HTH, John.
