Currently, we are enforcing the _FORTIFY_SOURCE=2 without any previous detection if the macro has been already defined, e.g. by environment, or is just enabled by compiler by default on some distributions (e.g. Gentoo). This could result in the error like this: <command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror] <built-in>: note: this is the location of the previous definition Tracked-On: #2344 Signed-off-by: Tw <wei.tan@intel.com> Reviewed-by: Binbin Wu <binbin.wu@intel.com> Acked-by: Yin Fengwei <fengwei.yin@intel.com>
