[Buildroot] [PATCH 2/2] Provide PAM configuration files in the fs skeleton

[Dmitry <golubovsky@gmail.com>]

The default PAM configuration file requires valid user accounts with
non-blank passwords.

The PAM configuration file for busybox login allows local authentication
with blank passwords thus emulating the non-PAM login configuration.
