[manjaro-dev] C++ ABI bump rebuild

[Philip Müller]

Hi everyone,

GCC-5.x release libstdc++ with a dual ABI [1].  The time has come to
rebuild everything C++ related to the new one after we merged the change
into [unstable]!

This means:
 - do not use [unstable] for anything else
 - do not update anything C++ until it is done
 - help fixing anything that does not build...

Archlinux used foutrelis rebuild tool to do the building. Given by the
curernt build status, all went fine[2] for Archlinux. So we have to
check which overlay packages are affected so we rebuild them before we
do anything else.

The need of build will start as soon as I synced the changes from
Archlinux. I will keep you updated on that matter.
