udhcpc / empty DNS config should not overwrite existing /etc/resolv.conf /3.12.1

[aheissenberger]

This behavior is different to the behavior of the DHCP Client under
debian/ubuntu where an empty DNS entry will not delete the existing
/etc/resolv.conf

Have a look at this for more infos and a suggested solution:
http://forum.tinycorelinux.net/index.php/topic,16482.msg98078.html#msg98078

Is this a bug or a valid behavior of tiny core linux?
The problem is very common in a typical virtual host setup with eth0/NAT and eth1/hostonly network configuration. It is very easy to simulate in virtual box.
