Docker Build Support for Proxies
Docker Build Support for Proxies

Modifies the makefile and uses a chain of GNU conditionals to support environments behind firewalls/with proxies.

If the environment variables are set, then it will use them. If they are not set then make will run docker build normally. No modifications are necessary in the Dockerfile since Docker has [pre-defined variables](https://docs.docker.com/engine/reference/builder/#predefined-args)
