As I suggested in another reply, I think we should add 'b2 headers' to the
testing scripts as a hotfix. I'd create a pull request, but I have no idea how
the testing works and where this command should be added.
The long term fix is probably figure out why the headers target is not built
first before process_jam_log (I described my theory in another reply) and fix
it. This will probably require attention of the Boost.Build team.
