Base image make/build broken in 9.1.3 branch, works in master

[liz72703]

When I clone the 9.1.3 branch and do make build-advancedserver to build a base image it fails.
However, if I clone the master branch, the build works fine without any errors.

UPDATE: I did get this branch to work on another Linux server. I only encountered this issue on a system running Ubuntu 18.04.

Error with 9.1.3 branch:
