Subject: [PATCH] Add hostname-labeled loopback entries for DHCP

This addresses a regression since the netconfig in Slackware 14.2. Previously,
when selecting to configure the machine with DHCP we would have entries with
the loopback addresses that were labeled with the machine's hostname.
Without these, a machine will not be able to contact itself using its own
hostname unless something else is providing matching name service, and we
do not want to have to rely on this.
