Well, Boost is mostly a header-only library, in particular the asio
stuff I believe. While we have sub-options for the parts of Boost that
are not purely headers, we don't have any sub-options for the parts of
Boost that are just headers.

So, the options are either to add sub-options to Boost, or to make
Boost as a whole only available on NPTL toolchains. The latter is a bit
annoying as it would mean adding this dependency to all Boost reverse
dependencies, even those not using asio.

So I think Fabrice's patch is the best solution we can have today. I'm
not saying it's perfect, but it's good enough IMO.

Best regards,

Thomas
