Gitlab CI Clang 3.8 cxx11 abi
It seems the alpine linux running on the Gitlab CI builder has cppunit build using g++ without dual abi support. Meaning that exported symbols of the cppunit library are only using newer cpp11 abi. (c++ standard library is build with dual abi support luckily.) Meaning that anything compiled by clang 3.8 (3.9 should not be affected) is failing to link against cppunit's shared library.
For now lets just leave it as a informative issue here.
