One small hint for compilation time

[Jaime Torres]

My goal is not to speed up compilation by 1/3, but to spped up compilation
time.

Last time I have compiled kde 3.2.1 I have used -Os (with gcc 3.3.3), not
-O2 neither -O3.

Disabling the -Wall is as speedy as redirecting the stderr and stdout to
>/dev/null ?

Regards.
