Unable to use on NixOS or Alpine due to dependency on libc

This issue is equivalent to this issue in Aspect's Bazel lib: https://github.com/aspect-build/bazel-lib/issues/701

The coreutils toolchain currently used (from uutils) is linking against glibc on Linux. This fails on some platforms (including NixOS) and is not actually hermetic. Uutils has a statically linked variant of coreutils available as an alternative release artifact. Could the ruleset use this (either by default or as a configurable option)?
