'-fstack-protector-strong' is supported as of gcc-4.9.x - unless you upgrade, you'll forced to use the regular one. If you want more information on the option take a look here: http://www.outflux.net/blog/archives/2014/01/27/fstack-protector-strong/ I think it's not even that unlikely that you don't even want the strong version.
