Native packages cannot be used during cross-compiling. However, Qt still unconditionally tries to find them, which causes issues in some cases, such as when [cross-compiling from macOS to Windows](https://github.com/bitcoin/bitcoin/issues/32346).

This PR explicitly disables this unnecessary Qt behaviour.

Fixes https://github.com/bitcoin/bitcoin/issues/32346.

Here is a full workflow on my macOS Sequoia 15.4.1 (Intel):

% gmake -C depen

I'm struggling to reproduce the 'execve failed: Not a directory (20)' error message on Ubuntu 24.04:

```
$ bitcoind -daemon -signet -signer=fake.py
Bitcoin Core starting
$ bitcoin-cli -signet enumeratesigners
error code: -1
error message:
execve failed: No such file or directory (2)
```

Thanks! Took a variant of that, while still maintaining support for shortened forms of `--tmpdir`. The Python `ArgumentParser` supports doing that and I've personally used `--time=2` in place of `--timeout-factor=2` since it's shorter and I don't remember if it's `--timeout_factor`.

Quoting from https://github.com/bitcoin/bitcoin/issues/31942#issuecomment-2801696317:

> ... a recommended debugging step is to discard any cached results from an existing build directory...

And in this particular case, I don't think that CMake cache is worth reusing.

But this doesn't just match prefixes, it makes every parameter optional, so the middle one can be missing - which would be weird.

Maybe you meant `--tm(?:p(?:d(?:ir?)?)?)?=` which would only match the prefixes
* `--tmpdir=`
* `--tmpdi=`
* `--tmpd=`
* `--tmp=`
* `--tm=`

but the intermediary letters aren't optional, so
* `--tmr=`
won't be matched (and the groups are non-capturing so you can still use `m[1]` for the value)

Switched to use `os.linesep` which I think is more idiomatic... But I'm not entirely happy with how I ended up having to escape:
https://github.com/bitcoin/bitcoin/blob/b19439b1eee57041fc37dcf509d5ee9f248263bc/test/functional/feature_framework_startup_failures.py#L76-L79

It's a side-effect of using `repr(e)` in 28e282ef9ae94ede4aace6b97ff18c66cb72a001 which gives the escaped form.

Thanks for catching that. I would have leaned towards `--tm(p(d(i(r?)?)?)?)?=` but I like the non-capturing groups, don't recall coming across them before. Taken.

Prefer this alternative of switching to an iterative algorithm (instead of bumping the stack space #32349).

On master we do a depth-first gathering of challenges, the new stack based version does breadth-first, but result is put in a `std::set` so traversal order does not matter.

In bd89f7eff0dc6c44c6a0b96883c3816fe0919f95, why not just:
```C++
BOOST_CHECK(challenges_recursive == challenges);
```
?
https://en.cppreference.com/w/cpp/container/set/operator_cmp claims the complexity is linear with the size.

Was curious how this issue was introduced. Seems like it's existed for some time but was found by #32339 momentarily switching some Windows CI to use Debug configs. Would it be worth adding to the description instead of just "ref: #32339"?

The error seems to be intermittent, because now it looks like the centos task passed. (For reference, the failure three days ago was https://github.com/bitcoin/bitcoin/runs/41112451543)
