scripts in /build should run on any CI technology

[glennmusa]

Benefit/Result/Outcome
An IT Admin may have many CI and automation tools at their disposal. The scripts in /build should be flexible enough to permit that.

Description
For example, running the build scripts on an Azure DevOps Pipeline today do not work out of the box because ADO Pipelines use a different syntax to access environment variables (ADO Pipelines use 'macro syntax' $(myvariable) where GH Actions use plain bash syntax $myvariable or ${myvariable}).

Acceptance Criteria

• Refactor the scripts in /build such that they take arguments for execution instead of relying on underlying environment variables.
