Hopefully @hswong3i can figure this out.

containers/conmon#218 (comment)

[hswong3i]

This PR introduce 3 changes:

• Upgrade Nix stable channel from 20.03 to 20.09.

  NixOS 20.09 released at 2020-10-27, see
  https://nixos.org/manual/nixos/stable/release-notes.html#sec-release-20.09
  for more information.

• Replace git with gitMinimal.

  All 6 projects (i.e. crun/conmon/skopeo/buildah/podman/cri-o) are
  having git as dependency for failsafe during bootstrap. BTW
  [20.09] git: 2.28.0 -> 2.29.2 NixOS/nixpkgs#104896 replace asciidoc
  with asciidoctor so trigger the dependency chain to glib and so
  failed (see below). Switching to gitMinimal skip this dependency
  chain to glib, which also speed up overall build process.

• Adding -pthread for glib

  conmon couldn't skip the error by replacing git with
  gitMinimal since it do depend on glib. Since glib trigger
  error message "undefined reference to 'pthread_create'", therefore
  adding pthread to CFLAGS could solve the problem.

@rhatdan the fail most likely related to outdated cache; BTW, the static build procedure in .cirrus.yml had been revamped since my original contribution, so I have no idea about how to expire the existing cache now :-S
