Good call!  After doing
  for cpu in `seq 0 3` do; sudo cpufreq-set -g performance -c $cpu; done
the a8-3850 runs configure in 37 seconds!

On the i7, after doing "./configure" once to warm up,
ondemand gives 31 seconds, performance gives 23 seconds.
So it's not AMD-specific.
'conservative' gives 26 seconds, halfway between the two.
