BUG: Unusual test failures (whitespace-related?) on ppc32 with numpy-1.25.1 #24239
Description
Describe the issue:
I get several more test failures with numpy-1.25.1 than I do with numpy-1.24.4 on ppc32:
- numpy-1.24.4: 15 failed, 25832 passed, 883 skipped, 31 xfailed, 7 xpassed, 387 warnings
- numpy-1.25.1: 71 failed, 34200 passed, 931 skipped, 31 xfailed, 6 xpassed, 709 warnings
It's worth noting that we've switched prematurely to building with Meson in Gentoo for 1.25.x, although I hope that's not relevant for this bug.
What's especially interesting is that a bunch of the failures seem to be whitespace related in TestArray2String.
There are some other errors in the log as well which look endianness related. Some of these aren't new to us (see https://bugs.gentoo.org/707116, #11831, #12638).
Reproduce the code example:
I've only reproduced this via the numpy test suite.Error message:

### Runtime information:
1.25.1
3.11.4 (main, Jul 5 2023, 00:34:18) [GCC 13.1.1 20230527]
### Context for the issue:
- Downstream Gentoo bug: https://bugs.gentoo.org/910739
- This affects us deploying newer versions of Numpy. Dropping Numpy on an architecture means dropping a very large number of packages, as it's often needed as a direct dependency if not as a test dependency.
