Comment # 2 on bug 1217883 from Thorsten Kukuk

Sicne there are some obscure valid use cases for udhcpc, I didn't disable it
but correctly configured the build options.
But there will be no script to set up the system network with the received
data, this is something the users have to do themself for their use cases.
udhcpc will not be supported as standard dhcp client.

I added notes about this to the package description.
