The implication here is that -pipe would make gcc significantly
faster, which is true only if the job is I/O bound. It is not.
Even if it were, a RAM-disk or MFS does a better job of reducing
the I/O bottleneck, because you are less likely to swap when you
can run the processes serially instead of concurrently.
