Dockerfile not working on aarch64 platform

First thanks for this great piece of software.
Only one small thing I noticed and want to inform you about:
I was not able to build docker image with the the given Dockerfile on ARM/aarch64
Adding download of newer config.guess version for the argtable buld did solve my issue:
