Adding #include "cli/common.ipp" to cli/cmd_test_test.cpp, 
cli/cmd_config_test.cpp and cli/cmd_about_test.cpp helps. Those files call 
a template function whose definition is not available.

Not sure. Maybe the inliner is more aggressive?

g++ used to leave an instantiation lying around, which it doesn't anymore.
