Théophane Hufschmitt f6142cd0d1 unset NIX_HARDENING_ENABLE in fast build mode
`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`.
