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
