boost: module context affected by GCC bug 64735

Browse Source 
Building boosts module context is affected by GCC bug 64735 [1]:

```
./boost/context/execution_context_v2.hpp:298:31: error: 'exception_ptr' is not a member of 'std'
     auto p = std::make_tuple( std::exception_ptr{}, std::move( data) );
```

This is because `exception_ptr` from libstdc++ is not available for
architectures not supporting always lock-free atomic ints.

Note, that this bug is fixed in GCC 7.
