/root/cca-v3-2/out-aarch64-sdk/.config includes a legacy configuration: BR2_GCC_VERSION_10_X=y Workaround method is comment: br-ext/configs/sdk-common:3:BR2_GCC_VERSION_10_X=y

Then we can finish the toolchain build, but will fail in build TF-A:

Looks that the GCC 13.3 is not compatible with some dependencies.
