It looks to me like 'llvm-config --ldflags' contains all of the flags
which llvm was linked with. For me this includes -lffi and -ldl. These
libraries may be needed to build llvm, but the are not required when
linking with llvm. So I do not want to use 'llvm-config --ldflags'
because it includes libraries that we do not need to link to.

They may be required when llvm is built statically. Building llvm as a dynamic library is supported under Windows (not sure about cygwin).
