Cross-compiling C++ for the ICnova AP7000 base (AVR32) - unresolved references

[higgins-demack]

Cross-compiling <myprog>.cpp (under Ubuntu with a buildroot toolchain) with 
avr32-linux-g++ produces a bunch of undefined references as shown below. I know 
it's something to do with libraries in the toolchain, but I can't track it 
down. Which buildroot options should I fiddle with?
