I'm starting to wonder if "configure" script being shipped with Boost is
a good idea. The idea is to make standard "./configure && make" work, however,
as above posting shows, "configure" is associated with various 
expected behaviour, and unless we want to duplicate all such behaviour,
we can end up confusing users.
