This is no longer true as of GNU make 3.81 (released in 2006). GNU
make artificially adjusts the load average based on the number of jobs
started in the last second, to avoid this issue.
In the next release of GNU make a different method, based on /proc, is
used for Linux specifically which should result in even better behavior
there.
Cheers!
