[boost] Noisy boost jamfiles

I'm using boost-build to build my own code as well as any Boost
libraries I link to.

At the end of this message is an example log I'm getting, every time I
build anything. Note, I am not even using boost regex or boost thread
in this case.

Is there justification for all this garbage?

Thanks,
Emil Dotchevski
