Guys,

We use boost.build not only for building boost but also to create own
binary packages. For a long time I observe linker errors on msvc due
to lack of usage requirements in Jamfile's.
Issue is reproduced when somebody builds executable like this:

exe foo : main.cpp /boost/filesystem ; #or /boost/program_options or
/boost/iostreams

Following trivial patch resolves these issues:
