Improve building on Linux with parallelization

[mehmetoguzderin]

Current cofiguration can easily drain system resources, leading to process getting killed.

Parallel builds use more system resources, not less.

@NeedsMoar when I created the issue it was to limit number of parallelization for certain stages such as linking under memory constrained environments to have process complete while not resorting to entirely single threaded execution. Didn't mean to imply parallelization would use less resources, rather use resources in a way so that build completes.
