Also if you dont want to do thos globbaly for all your packages you can make 
use of /etc/portage/env/. 
For example this is what i have for amarok in 
/etc/portage/env/media-sound/amarok

CFLAGS="-march=core2 -O1 -g"
CXXFLAGS="${CFLAGS}"

FEATURES="splitdebug"

also note when doing it this way, you will also have to do this for a few 
dependencies that amarok uses. The way i did it was, When dr konqi pops up 
after amarok crashes, it displays a list of files needed for a more usefull 
backtrace (in the developer information tab).Use equery to find out which 
packages those files belong to and add an entry in /etc/portage/env for them. 
After thats done rebuild those pacakges.
