In order to harden the build and the overall security of the project, this patch enables FORTIFY_SOURCE optimization in case the flag --enable-debug is not detected. Indeed, when debug is enabled, the -O flag is set to -O0, and the option FORTIFY_SOURCE expect at least -O1 to be properly enabled. Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com>

I'm not sure I'd call it an 'optimisation' - more of a 'feature' :-) , but - nice! |

@grahamwhaley I called it optimization because it is a compiler optimization that can only be used if at least -O1 is enabled. |
