Build fails on FreeBSD 14.3

[mmayer]

Under certain conditions, building coreutils on FreeBSD 14.3 fails. This is with

$ rustc --version
rustc 1.88.0 (6b00bc388 2025-06-23) (built from a source tarball)

If I run

make PROFILE=release MULTICALL=y

on my FreeBSD 14.3 box, the build eventually fails with:

[...]
   Compiling ctor v0.4.2
   Compiling uu_ls v0.1.0 (/home/markus/Developer/coreutils/src/uu/ls)
   Compiling bitvec v1.0.1
error: failed to run custom build command for `fts-sys v0.2.16`

Caused by:
  process didn't exit successfully: `/home/markus/Developer/coreutils/target/release/build/fts-sys-144c9c8bab512dd3/build-script-build` (exit status: 101)

At the same time, running

$ cargo build --release --features unix

works just fine.

It is worth noting that there is no libclang.so under FreeBSD. I am not sure why it is trying to use it during the build with "make" and why it is different to the build with "cargo".

Build of fts-sys crate fails. fts-sys is used in chcon tool which is compiled by default when using make.
You can install clang with pkg install llvm, but the build will still fail as chcon is only available in Linux.

I think it makes sense not to build the selinux tools on FreeBSD.
