 The problem is that that defconfig file (sourcery-arm-thumb2.config) doesn't
specify which toolchain to use:

BR2_arm=y
BR2_cortex_a8=y
BR2_ARM_EABI=y
BR2_ARM_INSTRUCTIONS_THUMB2=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TARGET_OPTIMIZATION=""

It just relies on the default external toolchain.

 Obviously this isn't very robust to begin with: when the external toolchains
change, this could implicitly change this toolchain defconfig. E.g. imagine that
Linaro would grow a Thumb2 option, then suddenly this sourcery-arm-thumb2.config
would build using a Linaro toolchain...

 So I think the solution is to explicitly add the predefined external toolchain
to use to all the toolchain configs. I'll try to send a patch for that.

 BTW, I notice now that we don't have configs for the Codescape toolchains. Any
reason for that?

 Regards,
 Arnout
