Feature request: Skip binary validation when builder is not used for any language #831
Description
Describe your idea/feature/enhancement
Basically as an extension of #678, which was fixed by #830. The issue is that for a given build system we don't really need to have the language binary available to us if all we're doing is copying the source files into the build directory. In #830, this was fixed by checking if dependencies needed to be resolved, and if they didn't we don't need to validate the binary existing because we're only copying the source files. This same flow could be true of other languages.
Proposal
Same as #830 but for different languages.
