You got the basics of it, adding PIC will probably help, although this
should be enabled by default for -O2, but I see you have -Os set as
well in the flags to GCC. Try adding -mrelax and see what happens.

What does not work? 4.2.2 works fine for me, and it is the latest
toolchain from Atmel. Although you must use the toolchain generated
with all the fixes applied (like Buildroot for AVR32 v2.2.0 does).

You could try to spin the entire Buildroot package from Atmel, since it
is based on a fairly new snapshot (20080924 IIRC).
