These are the fifth copies of {arch}/tizen-fetch.sh and {arch}/tizen-build-rootfs.sh files. They are duplicates of each other with few lines of differences. Can we deduplicate this code by having just one of each and pass architecture as positional argument?

./tizen-fetch.sh $TIZEN_TMP_DIR $arch
if [ "$2" = "x64" ]; then do_something_differnet; fi

@am11 Thanks, I agree. It's time to unify these scripts.

Nice cleanup! 👍

nit: align style with build-rootfs.sh (4 spaces indentation, case-esac for switching etc.)

LGTM, thank you for the consolidation!
(we can wireup build-rootfs-android the same way some day 💡)
