In general, settings that work on an older CPU will work on a newer
CPU of the same family. In specific, I'm pretty sure those settings
will work on your Athlon XP.
To find out the currently preferred CFLAGS for your box, do this.
# emerge genflags
# /usr/sbin/info2flags
CHOST="i686-pc-linux-gnu"
CFLAGS="-march=pentium4 -O3 -pipe"
CXXFLAGS="-march=pentium4 -O3 -pipe"
You can copy the variables into /etc/make.conf and as you update your
system, more and more of it will become optimized for your new box.
