Reduce number of parallel builds
With recent introduction of C++ code required memory for each compiler
instance has significantly increased causing build issues.
Currently build system spins 2 compiler instances per logical CPU core.
As CPU can hardly execute more than one thread at a time, it should be
pretty safe to change that formula so it doesn't multiply number of cpu
cores by 2 and such change will signifucantly reduce amount of memory
needed.
