See my post with subject "Optional targets" that describes the issue in more 
detail. For this specific case, you can add extra generator:

     generators.register-linker msvc.link.resouce-dll

        : OBJ SEARCHED_LIB STATIC_LIB IMPORT_LIB
        : SHARED_LIB
        : <toolset>msvc <resource-only>yes ;

and then add

  generators.override msvc.link.resource-dll : msvc.link.dll ;

Then, with <resource-only>yes, only the second generator will be used.
