cmake: prefer LLVM 3.4 over system-wide default

Browse Source 
FindLLVM.cmake now starts searching for specific "llvm-config-x.y"
versions instead of using the system-wide default "llvm-config" first.
This avoids breaking builds on Debian 8, where LLVM 3.5 is the (yet
unsupported) default, but 3.4 is still installable.
