opkg update signature check fails

technically, yes. but you can fix it by changing /etc/network/interfaces  
-- the part for usb0 does an echo to /etc/resolv.conf inserting  
192.168.0.200, switch that to your dns' number.

the *.sig files are not available at all. so if opkg does complain over  
the sigs only, that's ok.
if you can ping any other url and it's resolved than any fault should be  
entirely on the buildhost's side.
