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,
