That's the GCC-5 transition, unstable is broken as it's supposed to. You
can use testing if you're bothered by uninstallable packages (or any other
form of the sky falling).

Static linking has no place in a distribution. Among numerous other
downsides, any update of a dependency requires a "rebuild world". There's
no way to make a security or bugfix update without such a mass recompile.
