We use a self-build toolchain from some older buildroot which has

 * avr32-linux-gcc (GCC) 4.2.2-atmel.1.1.3.buildroot.1-20100804
 * GNU ld (GNU Binutils) 2.18.atmel.1.0.1.buildroot.1

gcc got another patch to have the build date in version string.

So you do not have a *-linux-* toolchain?

Maybe ... I guess since I could build working binaries with my toolchain
something toolchain related is going wrong.

Maybe have a look for
http://distribute.atmel.no/tools/opensource/avr32-gcc/ (the script
should build a uclibc toolchain) to get another toolchain.
I had a short look for these patches some days ago cause we are hunting
another maybe toolchain related problem. AFAIK there are some different
linker settings. The avr32-linux toolchain does set the processor to
ap7000 (is it -m?) but the avr32-elf (which uses newlib) does not set
ap7000 as default. Maybe this could be the solution for your problem.
