[Andrew Lutsenko <anlutsenko@xxxxxxxxx>]

I will test later today both options
1. Removing VECTOR2::operator<< or renaming it to str() if it's used.
2. Upgrading to swig 3.0.10 from backports.

Hopefully first is doable and would be transparent for users.
Second one should definitely solve the issue and I feel like compared to
other hoops a user has to jump through to make KiCad compile on debian8
this would not be the worst.

Regards,
Andrew
