When building MongoDB core r3.2.7 against Boost v1.61.0, the build fails, with the following error:

src/mongo/db/ftdc/compressor.cpp:50:31: error: no matching function for call to 'boost::none_t::none_t()'
return

{boost::none_t()}

scons: building terminated because of errors.

I'm guessing this is due to boost::none_t() needing to be replaced with boost::none, and will attempt patching the source, to see if that works.

This also means it would break against Boost v1.60, as that version requires the same change. This means MongoDB does not built against the latest version of Boost.
