Hello Mark, 

Thanks much for your help,

target/linux/Makefile.in.advanced contains the following: 
$(LINUX26_DIR)/.configured: $(LINUX26_DIR)/.config
	$(SED) '/CONFIG_AEABI=y/d' $(LINUX26_DIR)/.config ifeq ($(BR2_ARM_EABI),y)
	echo "CONFIG_AEABI=y" >> $(LINUX26_DIR)/.config
	$(SED) '/CONFIG_OABI_COMPAT/d' $(LINUX26_DIR)/.config
	echo "# CONFIG_OABI_COMPAT is not set" >> $(LINUX26_DIR)/.config else

... and my configuration files look fine to me:
$ make saveconfig
(...)
$ cd local/logica_demo/
$ grep ABI *
linux-2.6.28.config:CONFIG_SLABINFO=y
linux-2.6.28.config:# CONFIG_AEABI is not set linux-2.6.28.config:# CONFIG_SECURITY_FILE_CAPABILITIES is not set logica_demo.config:BR2_ARM_OABI=y logica_demo.config:# BR2_ARM_EABI is not set logica_demo.config:BR2_GCC_TARGET_ABI="apcs-gnu"
uclibc-0.9.30.1.config:CONFIG_ARM_OABI=y
uclibc-0.9.30.1.config:# CONFIG_ARM_EABI is not set

... and the toolchain looks OK too : 
$ ls -l $( which arm-linux-gcc)
lrwxrwxrwx 1 damien damien 20 jui 29 14:58 /mnt/fractal/buildroot/buildroot-2009.05/build_arm/staging_dir/usr/bin/arm-linux-gcc -> arm-linux-uclibc-gcc

Do you see something else to check?

Best regards,
Damien
