What's the problem? Describe what went wrong.

Attempting to compile Dolphin 5.0-rc will result in ld attempting to link against LLVM 3.7.0, albiet improperly.
This causes linking to fail.

What steps will reproduce the problem?

git clone https://github.com/dolphin-emu/dolphin.git
cd dolphin
git checkout 5.0-rc
wget https://github.com/dolphin-emu/dolphin/commit/8c5744bca705a0895bd51c966a30171ee2bab43a miniupnpc.patch
patch -ui miniupnpc.patch
mkdir build
cd build
cmake ..
make

Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?

This effects 5.0-rc. Both 4.0.2 and 9999 (git) are unaffected

What are your PC specifications? (CPU, GPU, Operating System, more)
