Make build error about docker-opengl

[jamesbrink]

Sorry for late response, this appears to me like its simply a lack of resources on build machine

Killed signal terminated program cc1plus

@adamwhitson if you are using docker for macOS, try giving the docker VM more memory. The alternative would be for us to disable the concurrent build, but this still will not guarantee memory won't be exhausted. This is very typical in nodejs builds, and even more so haskell builds... when memory is exhausted you will simply see an error like the above.

No worries @jamesbrink . I appreciate you taking the time to respond. I will give that a try. Thanks!

@adamwhitson I will close the issue, but if you find that low memory is not the case, or if others feel we should adjust the build and remove the concurrency feel free to re-open this issue and we can make those changes. The concurrency speeds up the build but I will also do a quick comparison for each, or maybe make it optional to build concurrently
