The error is about missing RTTI support (C++ runtime type
information). The C bindings are just a layer around the C++ LLVM
libraries. More specifically, the LLVM libraries must be linked to the
C++ runtime to work. So use g++ for linking or pass the C++ runtime
libraries on the link command (stdc++ and maybe some other).
