Buildroot for ICnova AP7000 Base (Grasshopper)

OP #2305580
Has anyone been successful in building a toolchain (with C++ compiler) 
and a root image from the ICnova 20110104 support CD, on a Ubuntu 
10.04.3(Lusty) host? I know about the "getline" problem, and the fix for 
it, but I keep geeting all sorts of other cryptic bombouts. Any success 
stories, with tips on how you got there, would be greatly valued.
OP #2305798
Here's the error that currently has me completely confounded. FYI, the 
file 'as' has one line of actual script, 'exec "$@"'

sorry, no idea, ask in www.avrfreaks.net or Ic-Nova direct.
