Subject: [PATCH] scripts/tags.sh: don't rely on parsing `ls` for
 $ALLSOURCE_ARCHS generation

Parsing `ls` is fragile at best and _will_ fail when $tree
contains spaces. Replace this with a glob-generated string
and directly assign it to $ALLSOURCE_ARCHS; use a subshell
so `cd` doesn't affect the current working directory.
