Not sure when it became that way, but it seems to be set by default, just compile anything using `g++` (first thought was it related to C++ standard, but it isn't):
```c++
#include <iostream>

int main()
{
std::cout << _GNU_SOURCE << std::endl;
std::cout << _POSIX_C_SOURCE << std::endl;
return 0;
}
```

```bash
$ g++ --version
g++ (Ubuntu 13.3.0-6ubuntu2~24.04) 13.

Previous thread: https://github.com/bitcoin/bitcoin/pull/32326#discussion_r2058445224

`AlreadyConnectedToAddressPort` is significantly more verbose than master's `FindNode`. Checked for uses of `Is[A-Z]\w`-prefix and the `Already`-prefix seems to rarely work, meaning `Already` is more specific in this case. This convinced me that `Already` might be fine. :+1:

@laanwj you might remember / know of such systems?

Yes. At the time there was cloudabi, which was a sandboxed version of POSIX that removed all contextual access and ambient authority, so processes only get capability handles passed in to what they need. So there was no shell and hence no `std::system`. But that project was abandoned years ago.

i'm not sure any other such platforms exist right now, i'm fine with removing the check. But adding a comment makes sense nevertheless.

This PR is an extension of https://github.com/bitcoin/bitcoin/pull/32296 (which originally just removed the unnecessary `prevector` suppression, but @maflcko bisected the cause and removed the dead code as well).
Your reviews would be appreciated there as well.
