unable to fix Arm EABI in UClibc Menuconfig

Hi All,

With new buildroot snapshot, whatever i do to set ARM Target as EABI - it
reverts back to OABI because of which i am getting below mentioned error. I set it to ARM EABI "Make menuconfig & make uclibc-menuconfig". i tried setting manually in uclibc-9.29.0.config & uclibc-9.29.0-wchar.config. If i set it manually in buildroot/toolchain_build_arm/uClibc-0.9.29 & then go to "make uclibc-menuconfig" still it reverts back to ARM OABI.

Kindly help me to solve this. I didnt face this in last weeks Snapshot(of around last wek thursday). but from oday its happening.

This is my buildroot .config

BR2_arm=y
BR2_arm926t=y
BR2_ARM_TYPE="ARM926T"
# BR2_ARM_OABI is not set
BR2_ARM_EABI=y
BR2_ARCH="arm"
BR2_ENDIAN="LITTLE"
BR2_GCC_TARGET_TUNE="arm9tdmi"

When I used buildroot (Jun 2007) and pre-prepared files (.config with BR2_ARM_EABI=y and uClibc-0.9.29.config with CONFIG_ARM_EABI=y), I ran into similar behavior:
After unzipping buildroot and then copying the files to the appropriate locations, starting a build / doing menuconfig would, at some point, always change uClibc config back to OABI, causing this error you describe. However, when just manually changing it back to EABI then and restarting the build, eventually it would build fully. As the buildroot documentation talked about getting the full build only in several config / build steps, I did not pursue this any further.
