As I explained already, this is not a solution, as we have supported platforms
which are not compatible with the current boost, and we even have at least one
which is not compatible with anything newer than the boost version newer than
our boost(_cropped).
So this is not a solution. The right solution is to go platform-dependent and
use an external boost.
(please don't consider building a full gcc toolchain on the platforms which
can't take a new boost as a solution, because it's a disaster).
