fix #3500 CMake 3.18 or later was required by #3392. Because it uses `CheckLinkerFlag`. But requiring CMake 3.18 or later is a bit aggressive. Because Ubuntu 20.04 LTS still uses CMake 3.16.3: https://packages.ubuntu.com/search?keywords=cmake This change disables `-z noexecstack` check with old CMake. This will not break any existing users. Because users who need `-z noexecstack` must already use CMake 3.18 or later.
