Solved it by commenting out lines in ~/yocto-ml-build/bsp-toradex/build/tmp/work/aarch64-tdx-linux/arm-compute-library/21.02-r0/recipe-sysroot-native/usr/bin/…/…/usr/lib/python3.8/site-packages/SCons/Script/Main.py which use sysconfig.
sysconfig is only meant to be used to put out a message in above file, hence commenting it out does not cause any worries.
