scripts/Makefile.lib just does:
ifdef CONFIG_SYMBOL_PREFIX
so you should do the same
that said, cmd_depmod is just a shell command. and you're running another
script helper (depmod.sh). how about passing it unconditionally ?
cmd_depmod = ... -P "$(CONFIG_SYMBOL_PREFIX)"
since the default will be "no prefix", using -P "" is the same thing.

you can do:
DEPMOD=$1
KERNELRELEASE=$2
shift 2

you could do instead:
later=$(printf '%s\n' "$version" "3.13" | sort -V | tail -n 1)
