If your somewhat old machine has more than one core, using "make -j x"
with x the number of core, might speedup the wall-time of the compile.
the load would be the same, but the difference for the one between the
screen and the chair might be appreciated.

Of course, using more than one core means hotter cpu (but for less
time... all might be a question of balance)
