test_svm fails on i386 with scipy 1.13

### Describe the bug

scipy 1.13 is triggering test failure in test_svc_ovr_tie_breaking[NuSVC] on i386 architecture.

The error can be seeing in debian CI tests, https://ci.debian.net/packages/s/scikit-learn/unstable/i386/
Full test log at https://ci.debian.net/packages/s/scikit-learn/unstable/i386/50043538/
or https://ci.debian.net/packages/s/scikit-learn/testing/i386/50043537/


### Steps/Code to Reproduce

On an i386 system with scipy 1.13 installed
```
$ pytest-3 /usr/lib/python3/dist-packages/sklearn/svm/tests/test_svm.py -k test_svc_ovr_tie_breaking
```

### Expected Results

test should pass 

### Actual Results

COMMENT:
For people interested in working on a fix, you should be able to reproduce the runtime environment that triggered the failure using docker and its builtin platform emulation:

```
docker run --rm -ti -v `pwd`:/scikit-learn --platform linux/i386 debian
```

People interested in fixing this issue should first check that they can reproduce the test failure after installing the `main` branch of scikit-learn in that environment and then attempt to refactor the test as suggested in https://github.com/scikit-learn/scikit-learn/issues/29633#issuecomment-2272914854.
