Passing -Wl,--threads=1 via -DCMAKE_CXX_FLAGS causes a config error.

-- Check for working CXX compiler:
/home/usr4/c74014i/opt/clang/current/bin/clang++ -- broken
CMake Error at
/home/usr4/c74014i/opt/cmake-3.16.3-Linux-x86_64/share/cmake-3.16/Modules/CMakeTestCXXCompiler.cmake:53
(message):
  The C++ compiler

    "/home/usr4/c74014i/opt/clang/current/bin/clang++"

  is not able to compile a simple test program.

  It fails with the following output:
