sys-libs/glibc includes a check for a 'files' provider for each database in nsswitch.conf in the ebuild.[1] This was intended to prevent login issues (etc.) when glibc-2.26 removed the 'compat' provider (which was re-added in glibc-2.27). This check is faulty for the following reasons: 1. It does not check for the provider that actually changed at the time.[2] 2. It should be ensuring that there is more than just a 'compat' provider. 3. Not having a 'files' provider is a valid configuration, which is even recommended on the wiki for LDAP/Domain managed computers.[3] 4. This check was made obsolete with glibc-2.27.[2] With this being the case, the check should be removed so that valid nsswitch.conf values do not cause build failures when glibc is updated.

The check for a files provider breaks on certain valid nsswitch.conf configurations. As the check was only required for =sys-libs/glibc-2.26 it has been removed.
