Steps to reproduce

[matthewcroughan@build05:~]$ ls result/lib/security/pam_lastlog.so
result/lib/security/pam_lastlog.so

[matthewcroughan@build05:~]$ nix build nixpkgs#pkgsMusl.pam

[matthewcroughan@build05:~]$ ls result/lib/security/pam_lastlog.so
ls: cannot access 'result/lib/security/pam_lastlog.so': No such file or directory
