regression: 3.12.1 broke coreutils gnu sort, replacing with busybox
I have a Dockerfile that adds coreutils because my image relies on gnu sort (specifically the --version-sort option).
However, when I build
FROM alpine:3.12 it now fails. If I build
FROM alpine:3.12.0, it succeeds. As of this writing, 3.12.1 is the most recent in the 3.12 series.
