bug#25879: [PATCH] gnu: Add LLVM and CLANG 3.9.1.

[Eric Bavier]

Thanks for the patch!

I have another package that needs 3.9 in its latest version, so I'm
interested in getting it merged.  Just one comment/question:

Does clang 3.9 not need the libc-search-path patch that is applied in
other versions?
