Config.guess/config.sub upgrade?

I tried to build the latest bk-bugfix release on a current Armbian Pine64 box (Debian 10-based) and got a lot of errors about how the cpu-vendor-OS returned by config.guess/config.sub was not found, and perhaps I should upgrade the copies of these scripts.

But I’m not actually seeing these scripts in the distribution.

Am I chasing down the wrong path?

What’s a better way to go here?

Oh, on this machine config.guess returns “aarch64-unknown-linux-gnu” while my wrapper returns “aarch64-unknown-debian10”. If I could figure out a good way to identify the glibc version then I’d be thinking hard about a way to add that information to the CVO string.
