LLVM's Makefiles aren't meant to be used in isolation. You'll probably
find LLVMHello.so was already built and installed as part of the
normal build process. If you change the source, you'd rebuild it by
running make from the overall build directory.

Alternatively, for passes you often only needusually only need to use
something as simple as"clang `llvm-config --cxxflags --libs --ldflags`
-fno-rtti llvm/lib/Transforms/Hello/Hello.cpp -shared -o Hello.so".

Cheers.
