pkg-config

I want to raise attention for my ticket
    http://llvm.org/bugs/show_bug.cgi?id=9405

Compiling the Haskell LLVM bindings is always a lot of trying around and patching, its configure procedure did not get better over the years. However, it would be straightforward if llvm paths could be queried via the pkg-config system. This is directly supported by Haskell's packaging system Cabal and I assume that this applies to other languages as well.

Thus my question: How about supporting pkg-config additionally to llvm-config?

Best,
Henning
