We want to evaluate whether shellcheck is useful in presubmits. As a first step, import the ebuild with whatever dependencies are needed to see what effect it will have on the chroot.
My initial trial run suggests that this adds ~200MB to the compressed SDK tarball and ~1.1GB to the uncompressed chroot. If we can change shellcheck to be statically linked, the needed runtime is ~20MB uncompressed and the rest is built-time-only dependencies. I'm looking into how much surgery in make_chroot.sh this would need.
