Before this commit LLVM 7 was supported, but only if one explicitly provided LLVM_CONFIG= and CLANG= paths. As LLVM 7 is the first
version that includes our upstreamed debugging and profiling features, and as debian is planning to default to 7 due to wider architecture support, it seems good to support auto-detecting that version.
