It seems I was right.
Boost libs for Arch Linux are not compiled using the standard C++14.
Because of this, Boost.Context cannot support Boost.Coroutine2.

I recompiled Boost-libs with C++14, then reinstalled and now the Fibonacci
example compiles and links correctly with the system libs.

I hope this helps other developers with similar problems.
