As explained to me by Steve Watanabe, I can keep from having a toolset 
execute targets as defined by an alias through target alternatives. But 
when I tried it, it did not work with the latest Boost Build. In a jam 
file I have:

alias ttivm16 : :
         <toolset>gcc-3.4.5
     ;

alias ttivm16
     :
         [ run test_vm_has_template_cp.cpp : : :
           <define>BOOST_TTI_VERSION_1_6
           <define>BOOST_PP_VARIADICS=1 ]
     ;

Yet when I ran:

bjam toolset=gcc-3.4.5 ttivm16

The test_vm_has_template.cpp target is compiled and run.
