CMake incantation and execution environment
SUMMARY
I configured dolphin 19.04.3 for building with the LLVM 5 toolchain (clang++-5
but also llvm-ar-5 and llvm-nm-5 as far as that's relevant).
For some reason this led to a link failure:
```

2. invoke make
OBSERVED RESULT
The error above.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Kernel 4.14.

ADDITIONAL INFORMATION
Explicitly linking in libdolphinprivate solves the issue, in src/CMakeLists.txt
:
target_link_libraries(dolphin
dolphinprivate
)
