`LLVM :: tools/llvm-cas/validation.test` test from `check-llvm` fails on Ubuntu 25.10 if coreutils are provided by uutils instead of GNU coreutils. Please note that this issue does not affect any LTS Ubuntu releases.
## How to reproduce
Start Ubuntu 25.10 container:
```bash
docker run --rm -ti ubuntu:25.10 /bin/bash
```
Inside the container, build LLVM and run tests (tested at commit `2a10e91d8f2edf20bb0e6680e668b327334dc6e8`):
```bash
sed --in-place -e '/^Types:/ s/deb/deb deb-src/' /etc/apt/sources.list.d/ubuntu.sources
apt-get update
apt-get build-dep -y llvm-toolchain-21
apt-get install -y git
git clone --depth 1 https://github.com/llvm/llvm-project.git
cd llvm-project
CFLAGS=-O1 cmake -S llvm -B build -G Ninja -DLLVM_TARGETS_TO_BUILD=X86 -DCMAKE_BUILD_TYPE=Release
ninja -C build
ninja -C build check-llvm-tools-llvm-cas
```
This produces the following error:
```
truncate -s -40 /llvm-project/build/test/tools/llvm-cas/Output/validation.test.tmp/ac/v1.1/actions.v1
# executed command: truncate -s -40 /llvm-project/build/test/tools/llvm-cas/Output/validation.test.tmp/ac/v1.1/actions.v1
# .---command stderr------------
# | error: unexpected argument '-4' found
# |
# | tip: to pass '-4' as a value, use '-- -4'
# |
# | Usage: truncate [OPTION]... [FILE]...
# |
# | For more information, try '--help'.
# `-----------------------------
# error: command failed with exit status: 1

Re-run tests with GNU coreutils:
```bash
apt-get install coreutils-from-gnu coreutils-from-uutils- --allow-remove-essential
ninja -C build check-llvm-tools-llvm-cas
```
Now there are no errors:
