You actually choose whether you want it to happen or not. With gcc, the
-mcpu option controls which processor family to optimize for
(instruction scheduling etc), and the -march option controls which
instruction set to use. By setting march higher than i386 you explicitly
say that "I know that I won't be able to run these binaries on lower
class boxes, so I hope you can make them a little faster in return".
This is why you can get your box running faster with source based
distributions than with binary. redhat compiles their binaries
-march=i386 -mcpu=i686, mandrake i think uses -march=i586 -mcpu=i686
