Bug#844093: clang-3.9: clang needs library LLVMgold.so from llvm-dev

[Norbert Lange]

Hmm, llvm-runtime is not a dependency either, still placing the
library in a -dev package with alot of headers
is not optimal?

I also worked a bit on the test script, with an installed llvm-3.9-dev
and the fixed efficiency sanitzier I get this output:
(just starnge taht the builtins get linked twice?)

$ sh testclang.sh clang-3.9 -v
