Add support for "-fstack-protector-strong". This extends the WITH_SSP_PORTS Makefile option in FreeBSD which adds "-fstack-protector" and "-fstack-protector-all" command-line options that add extra code to check for buffer overflows to ports built that way, cf. https://gcc.gnu.org/onlinedocs/gcc-4.8.3/gcc/Optimize-Options.html While this was a good first step, those switches offer too little protection or too much overhead and so Google contributed a balanced "-fstack-protector-strong".
