Subject: make_single_applets: fix ": $((fail++))" expansion error
$((fail++)) is not a required expression in POSIX, and in "dash" it
could produce an error like this:
./make_single_applets.sh: 61: arithmetic expression: expecting primary: "fail++"
Replace this with something portable: fail=$((fail+1)) would work.
