  -----------
  [libc] Silence warning about returning from noreturn function

The `exit` entrypoint calls into `quick_exit` which is marked noreturn
in some cases. This will cause errors because we then have control flow
externally. This warning can be silenced by using a
`__builtin_unreachable` instruction accordingly.
