In the future, we will Default to _FORTIFY_SOURCE=2 if SSP is enabled, otherwise default to _FORTIFY_SOURCE=0. For now we default it to 0 unconditionally to ease bisect across older versions without the new symbols, and we'll put out a call for testing. include/*.h include their ssp/*.h equivalents as needed based on the knob. Programs and users are allowed to override FORTIFY_SOURCE in their Makefiles or src.conf/make.conf to force it off.
