You should "install" the LLVM that you build yourself, e.g. by 
make install or ninja install. And then point LDC to that 
installation of LLVM instead of to the build dir. LLVM_ROOT_DIR 
should point to the installation dir, not to your build dir. That 
is the expected setup when building LDC. Can you try that?
