Alex Denisov d0c8d58527 Fix CMake configuration error when run with -Werror/-Wall ...

The following code doesn't compile

  uint64_t i = x.load(std::memory_order_relaxed);
  return 0;

when CMAKE_C_FLAGS set to -Werror -Wall, thus incorrectly
breaking the CMake configuration step:

  -- Looking for __atomic_load_8 in atomic
  -- Looking for __atomic_load_8 in atomic - not found
  CMake Error at cmake/modules/CheckAtomic.cmake:79 (message):
    Host compiler appears to require libatomic for 64-bit operations, but
    cannot find it.
  Call Stack (most recent call first):
    cmake/config-ix.cmake:360 (include)
    CMakeLists.txt:671 (include)
