bug#49459: [core-updates] Coreutils 8.32 test failures on armhf-linux

[Ludovic Courtès]

On ‘core-updates’ ca. 68b0e0d511c2873603636e9f783ff59aac4b7612,
(@@ (gnu packages commencement) coreutils-final) fails Gnulib tests like
so, when running “natively” on an OverDrive (aarch64):

--8<---------------cut here---------------start------------->8---
FAIL: test-perror2
==================

test-perror2.c:84: assertion 'msg3 == msg4 || STREQ (msg3, str3)' failed
FAIL test-perror2 (exit status: 134)

FAIL: test-strerror_r
=====================

test-strerror_r.c:170: assertion 'msg3 == msg4 || STREQ (msg3, str3)' failed
FAIL test-strerror_r (exit status: 134)
--8<---------------cut here---------------end--------------->8---

Regarding ‘test-strerror_r’, this is what I see with Guile:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> %host-type
$1 = "arm-unknown-linux-gnueabihf"
scheme@(guile-user)> (strerror -4)
$2 = "Unknown error -4"
scheme@(guile-user)> (strerror 1729576)
$3 = "Unknown error 1729576"
--8<---------------cut here---------------end--------------->8---

This is apparently fixed by this Gnulib commit:
