^^^_____________ Time to build.
Therefore, I decided to run a bunch of builds in a loop and accumulate
some times. The kernel was already configured then `make clean` was
executed. This was not timed.
Then `timer make bzImage &>World.Log &` was executed 8 times.
`timer` is a simple program that gets the time() variable, saves it,
then executes the rest of the command line (using system()), then
gets the time again. It subtracts the two times and writes them
before exit().

Linux-2.1.123 build times. SMP,
Build(1) 416 seconds
Build(2) 408 seconds
Build(3) 398 seconds
Build(4) 328 seconds
Build(5) 422 seconds

Mean 398 seconds
So it looks as though Linux-2.1.123 is quite a bit slower.
