[oe] [PATCH] netbase: add support for htcdream

[Denis 'GNUtoo' Carikli]

hi,
The default netbase's /etc/network/interfaces lacks 
auto usb0
So usb0 doesn't come up,and we can't ssh into the htcdream

Instead of changing the default netbase's /etc/network/interfaces,
I propose using the override system in order to make it work for 
the htcdream( so we would be using another /etc/network/interfaces 
for the htcdream)
*all the other machine do it like this
*it would have changed the default behaviour(which may not be wanted)

I sent a patch because I consider netbase as core,
nearly all the machines have an ovveride

Denis.
