I am using the original sources from boost.org (or from
boost.sourceforge.net, to be exact), file boost_1_34_1.tar.bz2 . The
Makefile is generated by the configure script when it is called first, so
it is that script that would have to be adapted.
I haven't checked whether this is the same situation on Windows. Probably
not, as "configure" is a shell script. On Linux, however, most people will
just say "configure; make;" in order to build the sources.

I am solely using Linux, so cannot comment on the situation on Windows. On
Linux however, the difference is marginal. The two compilation processes
just get 50% of the available compute time each. There might even be a
small benefit from "-j 2" on one processir, as computation and IO should
work concurrently for the two processes.
