BR fails to build native Toolchain for ARM

Hi all!

When using buildroot for arm, it fails to build a native toolchain with the following error:

/usr/lib/libgmp.so: could not read symbols: File in wrong format
collect2: ld returned 1 exit status

Config is gcc 4.2.1, binutils 2.17, uclibc 0.9.29
Build system is centos 5.

I tried various gcc versions in br, but every time got the same result.
