Why keeptemp keepwork noclean? keeptemp and keepwork are implied by noclean 
anyway so it's quite redundant. If you just want the source kept have a look 
at FEATURES=installsources in `man 5 make.conf`. Also have a look at 
FEATURES=splitdebug as already mentioned. test is unrelated but might of 
course be useful.

As mentioned by Daniel you can set FEATURES and CFLAGS on a per package basis 
in /etc/portage/env/$CATEGORY/$PN. Alternatively you can set it in a 
case; ...; esac construct in /etc/portage/bashrc (for multiple packages at 
once). Do note that variables here don't automatically stack so you need to 
either set everything you want or include $CFLAGS and $FEATURES.
