It's a stupid warning, but some ports enable it by default and were already defining _FORTIFY_SOURCE, thus exposing the new macros immediately. This at least fixes the libfido2 build, perhaps others as well. While we're here, fix a fresh build of stand w/ FORTIFY_SOURCE enabled by not pulling in the ssp headers if _STANDALONE is defined. We do not have runtime support in libsa as of the time of writing. Reported by: netchild Sponsored by: Stormshield Sponsored by: Klara, Inc.
