[Buildroot] linux .config : override: reassigning to symbol AEABI

Hello buildrooters!

I am trying to use buildroot for the ATEB9200 board form Embest. It is somewhat similar to the AT91rm9200dk/ek configs, including the CPU arm920t.

I am using the kernel v2.6.28, patched with the Atmel patched automatically applied by buildroot.
I am using buildroot v2009-05.

The kernel loading gets stuck after mounting the NFS root : 
================================================================
....
IP-Config: Complete:
     device=eth0, addr=10.84.34.8, mask=255.255.255.192, gw=10.84.34.1,
     host=debian_test, domain=, nis-domain=(none),
     bootserver=10.84.34.52, rootserver=10.84.34.52, rootpath=
Looking up port of RPC 100003/2 on 10.84.34.52
Looking up port of RPC 100005/1 on 10.84.34.52
VFS: Mounted root (nfs filesystem).
Freeing init memory: 116K
Kernel panic - not syncing: Attempted to kill init!
================================================================

I have configured buildroot to avoid EABI, and everything seems OK on this side in the config files.

I guess my problem comes from the kernel config, where the EABI symbol is overridden during buildroot compilation: 
=================================================================
make[1]: entrant dans le répertoire « /mnt/fractal/buildroot/buildroot-2009.05/project_build_arm/logica_demo/linux-2.6.28 »
scripts/kconfig/conf -o arch/arm/Kconfig
.config:1344:warning: override: reassigning to symbol AEABI
.config:1345:warning: override: reassigning to symbol IPV6
================================================================

I give to the kernel the following command line: 
root=/dev/nfs rw nfsroot=10.84.34.52:/mnt/fractal/buildroot/buildroot-2009.05/project_build_arm/logica_demo/root ip=10.84.34.8:10.84.34.52:10.84.34.1:255.255.255.192:debian_test:eth0:off init=/bin/sh

Do you think this is a normal behaviour, knowing that I did *not* configure buildroot, uclibc and the kernel for EABI?
Please let me know if you see options to dig into this problem.

Thanks for any help,
Damien
