It just calls check_c_compiler_flag [1], it's cmake being unhappy with the result. Then, it could use a C++ compiler instead of C but I don't know how likely you are going to convince upstream that it's a bad idea to build C++ as C with -x c++...

Same with 3.9.1
*** Bug 603878 has been marked as a duplicate of this bug. ***
I'm sorry but we can't provide proper support for multiple versions of LLVM packages. If you can still reproduce the problem with 7.0.1 series, please open a new bug.
