Oh, it's -march=native.

Paul Hartman just posted a link to a script that seems to do what I was 
looking for in the "[OT]eee 900a intel atom is what processor family?" 
thread: <http://www.pixelbeat.org/scripts/gcccpuopt>

But it suggests using -march=k8 - isn't that a 64-bit-only thing? I'm not 
compiling for AMD64, I'm still using 32-bit mode. So I have -march=athlon-xp 
in my CFLAGS for my AMD Athlon(tm) Dual Core Processor 4850e CPU.
