GCC 3.2.1 Optimizations and Via C3 Ezra CPU

I have a question regarding compiler optimizations for the Via
C3 Ezra processor. I did a little searching around on the web and found
CFLAGS="-march=i586 -m3dnow -O3 -pipe -fomit-frame-pointer"
CXXFLAGS="-march=i586 -m3dnow -O3 -pipe -fomit-frame-pointer"
Now, that makes sense to me. However, when I issue a "uname -m" on
this box, it reports that it is a i686. And sure enough, when I
compile gcc on this box, without any optimizations, it seems to be
identifying the host as i686-pc-linux-gnu. Any ideas what might be
going on here. Is gcc incorrectly identifying hardware on the box?
I'm using GCC 3.2.1. Or can I specify i686 in those three
