This NixOS code ensures that the system provide version-specific $LOCALE_ARCHIVE
environment variables to mitigate the effects of
NixOS/nixpkgs#38991.
To deploy it, copy the file into your /etc/nixos folder using a file name
like multi-glibc-locale-paths.nix. Then edit your configuration.nix file to
contain the attribute:
imports = [ ./multi-glibc-locale-paths.nix ];
