buildroot-20100922 config file

I'm using the latest snapshot of buildroot (buildroot-20100922) on Arch Linux. Target is an ARM (Xscale) machine, what I need is only the toolchain. Toolchain is generated without any problem.

I'd need a native toolchain on the ARM machine, which runs on ARM and creates output for the ARM machine. Buildroot seems to support this. These are switched on under "Package Selection for the Target --> Development tools":
-  native toolchain in the target filesystem;
- gmp;
- gmp headers;
- make;
- mpfr;
- mpfr headers;
- libtool;

See the attached file for the exact buildroot configuration I've been using.

Buildroot stops compiling native toolchain with the following error:

-------------------------------------------------------------

I made several attempts with buildroot-2010.08, buildroot-2010.05 and with this daily snapshot, but regardless of gcc selection, EABI/OABI, it always failed.

Please have a look at the problem, thanks!
