SubjectRe: [PATCH v3] scripts/tags.sh: don't parse `ls` for $ALLSOURCE_ARCHS generation

I do not like hard-coding the file(s) in arch/.

Don't you have an idea to list only directories?
'find -type d' or 'ls -F' or something?


For example, the following worked for me, I wonder
if there is a cleverer way...


# Detect if ALLSOURCE_ARCHS is set. If not, we assume SRCARCH
if [ "${ALLSOURCE_ARCHS}" = "" ]; then
ALLSOURCE_ARCHS=${SRCARCH}
elif [ "${ALLSOURCE_ARCHS}" = "all" ]; then
ALLSOURCE_ARCHS="$(cd "${tree}arch" && ls -1 -F | sed -n 's:/$::p')"
fi
