Pull request overview

Adds GNU-compatible uname -A/--all-labeled output (one labeled item per line) to the uname utility, including CLI wiring, localized help/labels, and regression tests.

Changes:

• Add -A/--all-labeled flag, plus labeled multi-line output formatting in uname.
• Add new localization keys for the flag help text and output labels (en-US, fr-FR).
• Add Rust tests for -A behavior and --all-labeled equivalence; update GNU fetch script to backport the corresponding GNU test.

util/fetch-gnu.sh:24

• sed -i plus \n and \t in the replacement string is GNU-sed-specific; on BSD/macOS sed this commonly fails or inserts literal n/t, which can corrupt all_tests and break make check. Consider switching this block to a more portable insertion approach (e.g., a small Perl/Python edit, or a POSIX-sed-compatible multiline insert), and avoid relying on \t escape handling in sed replacements.

# A test that does not exist in $ver at all is absent from its test list, so
# `make check` would silently never run it.  Register those in both the automake
# input and the generated Makefile.in: configure derives Makefile from the
# latter, and build-gnu.sh deliberately keeps automake from re-running.

src/uu/uname/src/uname.rs:79

• The output punctuation/spacing (": ") is hardcoded in code rather than localized. This makes locale-specific typography impossible (e.g., French commonly uses a space before :) and forces all locales into the same formatting. A more maintainable approach is to include the separator/format in the localized string (e.g., make labels include : / spacing, or use a single localized format string that takes { label } and { value }).

            out.push(translate!(label));
            out.push(": ");
            out.push(value);
            out.push("\n");

tests/by-util/test_uname.rs:154

• This test asserts English label text even though the implementation uses localized strings (translate!(...)). If the test runner environment ever selects a non-English locale, this becomes brittle. To make the test deterministic, consider forcing the locale for the invoked command (e.g., set LC_ALL=C/LANG=en_US.UTF-8 via the test command builder) or asserting against non-localized invariants (like line count + presence of values) rather than specific translated labels.

fn test_uname_all_labeled() {
    let result = new_ucmd!().arg("-A").succeeds();
    let stdout = result.stdout_str();
    // One labeled "Label: value" line per item. Like GNU, an unknown processor or
    // hardware platform is omitted, and we never determine either one.
    assert_eq!(stdout.lines().count(), 6);
    for label in [
        "Kernel name: ",
        "Node name: ",
        "Kernel release: ",
        "Kernel version: ",
        "Machine: ",
        "Operating system: ",
    ] {
        assert!(stdout.contains(label), "missing {label:?}");
    }
