arm64 and armhf

[Domavatus]

Hi,
i do some tinkeing of the undeliing Linux that 35XX+ is based on after aplying your Enhancement and SSH.
Trying to create swap, installing mc and even VPN to access NFS.
I do apt upgrade and it runs into problem that libc6 >= 2.4 is not found.
Some packages are arm64 and some are armhf.
So i added armhf to repositories declarations
"deb [arch=arm64,armhf] .... and do apt upgrade.
Packages are now upgraded and there is no longer problem with missing libc6.
