PATCH v2 1/1 package/clang: link libclang against libLLVM.so

libclang.so is statically linking against all LLVM static libraries instead of linking dynamically against libLLVM.so.

This patch fixes this problem by setting LLVM_LINK_LLVM_DYLIB to ON.

Changes v1 -> v2

*Avoid patching libclang's CMakeLists.txt
*Use LLVM_LINK_LLVM_DYLIB=ON
