Randy,
Thanks for the tip. Here's what I ended up with:
add_releaseinfo () {
sed -i "/NAME=/s/${DISTRO_NAME}/${DISTRO_NAME} (Debug)/"
${IMAGE_ROOTFS}/${sysconfdir}/os-release
}
ROOTFS_POSTPROCESS_COMMAND += " add_releaseinfo ; "

If you are willing to use a file other than os-release, I've often seen this
done using a function in ROOTFS_POSTPROCESS_COMMAND
https://www.yoctoproject.org/docs/1.7/ref-manual/ref-manual.html#var-ROOTFS_POSTPROCESS_COMMAND.
For example:
add_releaseinfo () {
echo "foo: ${FOOVAR}" > ${IMAGE_ROOTFS}/${sysconfdir}/somefile
echo "bar: ${BARVAR}" >> ${IMAGE_ROOTFS}/${sysconfdir}/somefile
}
ROOTFS_POSTPROCESS_COMMAND += " add_releaseinfo ; "
