Parallelize frontend and drivers build

[nemanjaglumac]

When we build using ./bin/buld.sh, we're executing a series of steps in sequential order. However, drivers and frontend don't have common dependencies, so they can easily be built in parallel. The frontend is the slowest part of the build. Drivers take a few minutes, and those few minutes is what we can save if we implement this.
