I tried this change as a quick test

     Fix compilation problems with some unit tests on Ubuntu 16.10+.
     Compiler produces position independent executables (PIE) by default
     which gets in the way of some unit tests.
     Fixes BZ#377066.

In https://bugs.kde.org/show_bug.cgi?id=377066

the compiler errors look similar to what you saw with clang.

I'll try to clean up all that.
