The toolchain builds just fine without the git repository (tested on windows and linux). We can skip setting up the repo and apply the patches directly when we aren't working on the toolchain itself. A flag `--dev` has been added for cases when git repo is needed. Without the flag, regular patch is applied. This significantly improves build times for first time builds.
