`NIX_HARDENING_ENABLE` causes `_FORTIFY_SOURCE` to be defined. This isn't compatible with `-O0`, and the compiler will happily remind us about it at every call, spamming the terminal with warnings and stack traces. We don't really care hardening in that case, so just disable it if we pass `OPTIMIZE=0`.
