        We have a rather large project composed of multiple final executables, 
and we're considering supporting compilation of both single and 
multi-threaded versions.  In our Jamroot, we have

project
    : requirements
          <threading>multi
          # some <define>s for different variants, and other stuff
    ;

So bjam debug -sthreading=single finds no targets to rebuild.[*]

        There is a default-build attribute for the project, but the only 
examples I've seen use it to determine which variant to build.

        Is there a simple way to tell bjam to compile with <threading>multi 
unless told otherwise?

[*] I also tried bjam debug threading=single, which I think is the new 
syntax, with no difference, obviously.
