Also to answer: Why is SDK_PREINSTALL insufficient for your customization?

yes we can append our toolchain via SDK_PREINSTALL, but i need to replace with the "crossbuild-essential-${COMPAT_DISTRO_ARCH}" , this one comes via SDK_TOOLCHAIN variable, if i append " gcc-multilib g++-multilib" without removing the crossbuild-essential am facing broken package problem.

Logs:

Eventually I need to remove crossbuild-essential, but this one will do via SDK_TOOLCHAIN remove override , but this does not work in the downstream layer, because always ISAR's python anonymous function wins and set its value.

Thanks,
