It seems that updating the sonic-sairedis submodule to bring in PR# 820 (https://github.com/Azure/sonic-sairedis/pull/820) will fix this build break. This update has already been completed on the 202012 branch

After looking at this further it seems that the libsairedis debian build for buster is linking with -lpython3.5m instead of -lpython3.7m. I believe stretch uses python3.5 whereas buster uses python3.7. We are seeing the same error in the 202012 azure pipeline build for marvell-armhf.
