Compilation broken on sparc in gentoo

[yhaenggi]

Tried to update i2pd today on my sparc machines, got failures with multiple version due to boost issues:

/usr/include/boost/asio/impl/executor.hpp:XXX:XX: error: ‘class std::reference_wrapper<boost::asio::io_context>’ has no member named ‘<...>’

-- Boost version: 1.72.0

Seems like it came from Websocket.cpp and WebSocks.cpp

Not our issue: zaphoyd/websocketpp#794

So, I tested with develop branch of websocketpp on Windows with MSYS2 using boost 1.72. Only on develop branch that issue was fixed.
Contact with webcryptopp package maintainer of your system.
