If you can, use the latest devkitArm (r25), which ships with a decent
default arm7 core - this lets you code just for the arm9 and it
simplifies a lot of the effort. If that's not possible, then Denis's
suggestion works a treat. I blogged a while ago on coding for the
Nintendo DS and using CMake, some ideas may help you out:
