Yeah, I came to the same conclusion. I used qlist and tar instead:
TARGET="powerpc-e300c2-linux-gnu"
MY_ROOT="/usr/${TARGET}"
mkdir -p /tmp/${TARGET}
qlist --quiet --all ${TARGET} > /tmp/${TARGET}/cross-tools
ROOT=${MY_ROOT} qlist --quiet --all > /tmp/${TARGET}/pkgs
#prefix all paths with our target root prefix
sed -i s:/:${MY_ROOT}/: /tmp/${TARGET}/pkgs
tar czf /tmp/${TARGET}.tgz -T /tmp/${TARGET}/cross-tools \
    -T /tmp/${TARGET}/pkgs

Would be nice if one could get rid of the sed hack by adding
an option to qlist to list the true abs path.
