Why should I use "native" if I know that my CPU is "athlon64" :P
Are you sure your cpu is not "athlon64-sse3"?
Look for pni in cat /proc/cpuinfo :-)

Here is my cpuinfo;
cat /proc/cpuinfo

I'm runing 64-bit so in my case I think it will be Athlon not Sempron:
CHOST="x86_64-pc-linux-gnu"
CFLAGS="-march=k8 -O2 -pipe"
am I correct?
