--- Comment #3 from Sam James <sjames at gcc dot gnu.org> ---
It's a bit easier with the following as you get many split libLLVM* linked into
unittests/CodeGen/CodeGenTests (which is a convenient reproducer I'm running):
```
-DBUILD_SHARED_LIBS=ON
-DLLVM_BUILD_LLVM_DYLIB=OFF
-DLLVM_LINK_LLVM_DYLIB=ON
```
