Kernel Compile Options

[Net Warrior <netwarrior863%gmail.com@localhost>]

Hi There Guys.

I was reading the example kernel config files to tune it up a little, 
for example remove stuff I do not need.
What I pay most attention is the flag related to CPU flags and the like, 
and I've got a doubt

makeoptions CPUFLAGS , reading the gcc man page it states that -march 
implies -mtune, so I'd like to know if the following is correct.

makeoptions CPUFLAGS="-march=athlon-4 -mtune=athlon-4" 

Is there something else that I should add to CPUFLAGS in order to 
optimize my enviroment?


Thanks for your time and support
Best Regards
