Comment (by hinder):

 GNU make has a -l option to specify a load threshold above which further
 tasks will not be spawned.  In principle this would solve the problem.  In
 practice I have observed it to severely underutilise the machine, with the
 load on the machine never approaching what I set it to.

   From man make:

          -l [load], --load-average[=load]
             Specifies  that  no new jobs (commands) should be started if
 there are others jobs running and the load average is at
             least load (a floating-point number).  With no argument,
 removes a previous load limit.
