Ok I was mistaken. It seems that the gnu++14 standard is only used by
default for GCC 6 release, which means that Boost.Context for Arch Linux
was probably not compiled using the C++14 standard.
The macro BOOST_NO_CXX14_INITIALIZED_LAMBDA_CAPTURES is defined if a
standard bellow c++14 is used and consequently,
BOOST_CONTEXT_NO_EXECUTION_CONTEXT macro is defined.

This is probably the reason why GCC is unable to successfully link the
Fibonacci example with the Boost.context system lib.
I will try to compile Boost for Arch linux, forcing the C++14 standard and
then report here my results.
