Use a better sorting algorithm
This change changes qsort() to use the same code as NetBSD and MacOS
because it goes 6x faster than Musl's SmoothSort function. Smoothsort
can still be used if you need something that's provenly linearithmic.
This change also improves GNU Make performance on whole by 7 percent!
