The release workflow now cross-compiles FreeBSD aarch64 inside the x86_64 VM (storytold/craft-common-actions#50) and sets CARGO_BUILD_TARGET=aarch64-unknown-freebsd. package.sh now reads the binaries from target/<triple>/release when CARGO_BUILD_TARGET is set, names the archive after the target instead of uname -m, and skips the --version run when the binary is for another architecture than the machine. x86_64 packages are unchanged. Part of storytold/craft-common-actions#39.

Explanation
The title names the main change: packaging the FreeBSD aarch64 cross build in packaging/freebsd/package.sh. The raw summary and PR objectives both center on aarch64 cross-build support, with CARGO_BUILD_TARGET-driven architecture selection and target-specific binary lookup. The parenthetical reference (craft-common-actions#39) is an external issue reference and does not describe the code change, but it does not make the title misleading. The title is specific and readable. It is 66 characters, slightly longer than ideal, which is acceptable.

Review comments at @packaging/freebsd/package.sh:
- Around line 33-44: Update the CARGO_BUILD_TARGET handling in release_arch’s
caller to validate that any explicit target is for FreeBSD before extracting its
architecture. Reject other target operating systems with an error and nonzero
exit, while preserving the existing host-architecture fallback when no target is
set.

…naries Review follow-up. CARGO_BUILD_TARGET must now be a *-unknown-freebsd triple, so a Linux or macOS target can no longer be packaged under a FreeBSD name, and it is read before uname -m, so an unsupported host does not block a valid cross build. When the binaries are for another architecture and cannot run --version, file(1) must report each as a FreeBSD ELF executable for the target architecture. Part of storytold/craft-common-actions#39.

- Line 124: Update the ELF match using $want and FreeBSD identity to also
require an executable ELF type, including PIE, and reject shared-library and
relocatable-object types so non-executable files cannot pass the

Review follow-up. The file(1) check for binaries that cannot run here now needs an executable (file says "executable" or "pie executable") or an ELF with an interpreter, which is how an older file(1) still shows a PIE it calls a shared object. FreeBSD libraries, object files and core files for the target architecture are refused. Part of storytold/craft-common-actions#39.
Review follow-up. With CARGO_BUILD_TARGET set on a host that is not FreeBSD (say an x86_64 Mac building x86_64-unknown-freebsd), the architectures match but the binary still cannot run, so the --version run is skipped there and the file(1) check is used instead. Part of storytold/craft-common-actions#39.
Review follow-up. CARGO_BUILD_TARGET must be aarch64-unknown-freebsd or x86_64-unknown-freebsd, the two the release builds; anything else, including made-up triples such as aarch64-foo-unknown-freebsd, stops with exit 2. Part of storytold/craft-common-actions#39.
Resolves the package.sh conflicts with main's SonarCloud cleanup: the cross-build changes are kept and use main's style, with [[ ]] tests and release_arch taking its argument as a named local and ending in an explicit return. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

What happens today
FreeBSD aarch64 was dropped from releases because the emulated aarch64 VM took over 5 hours. storytold/craft-common-actions#50 now cross-compiles aarch64 inside the KVM-accelerated x86_64 FreeBSD VM, opt-in through the
freebsd-architecturesinput ofrelease.yml. Its cross toolchain step exportsCARGO_BUILD_TARGET=aarch64-unknown-freebsdbeforepackaging/freebsd/package.shruns. With aarch64 turned on, this app's script would:uname -m, which is always amd64 in the guest, so the release job fails its archive-name check;$CARGO_TARGET_DIR/release, but cargo writes a cross build to$CARGO_TARGET_DIR/aarch64-unknown-freebsd/release;--version, and an aarch64 binary cannot run in the x86_64 guest (Exec format error, exit 126), which stops the script underset -e.Change
packaging/freebsd/package.shonly:CARGO_BUILD_TARGETwhen it is set (aarch64-unknown-freebsd→aarch64,x86_64-unknown-freebsd→x86_64), else fromuname -mas before;aarch64-unknown-freebsdorx86_64-unknown-freebsd(a Linux or macOS triple, a bare arch, another FreeBSD triple) is refused with exit 2, and the target is read beforeuname -m, so an unsupported host does not block a valid cross build;$CARGO_TARGET_DIR/${CARGO_BUILD_TARGET:+$CARGO_BUILD_TARGET/}release;--versionrun is skipped, with a message, when the package is for another architecture than the machine;file(1)must then report each staged binary as a FreeBSD ELF executable for the target architecture (an executable or PIE; libraries, object files and core files are refused). A FreeBSD target built on another OS (say an x86_64 Mac withx86_64-unknown-freebsd) also takes this path, since matching architectures do not make the binary runnable there (a--dry-runstill runs its stubs).Without
CARGO_BUILD_TARGETthe script behaves exactly as before, so x86_64 releases are unchanged. This PR does not opt the app into aarch64: that is a one-linefreebsd-architectures: '["x86_64","aarch64"]'in the release caller, to do once this is merged.stripis safe on the aarch64 binaries: FreeBSD 15.1's/usr/bin/stripis llvm-strip, which strips other-architecture ELFs. Tested in a FreeBSD 15.1 VM: it stripped a foreign-arch executable with exit 0 (the call keeps its|| trueanyway).Testing
