Custom Arch Linux Docker container for package builds via GitHub workflows. Available at https://hub.docker.com/repository/docker/qzed/archlinux.
Recent glibc updates on Arch break the official image running on hosts with kernels older than 5.8. This image replaces glibc with glibc-linux4 from AUR. See https://bugs.archlinux.org/task/69563 for the original bugreport, which has been closed as WONTFIX.
