seems a bit light on what actually is being used

random thoughts:
 - we've long defaulted to linking with relro
 - defaulting to bindnow is pretty much a no go for USE=-hardened
 - building everything as PIC/PIE comes with performance penalty for some 
architectures (e.g. x86), and is often the source of build issues with the 
hardened port
 - we've long defaulted to building with _FORTIFY_SOURCE
 - i'd need to see actual overhead data with SSP to see about enabling it by 
default
