what about wrapping the actual mergetool in a short shell script?
you already have a sh(1) after all:
% git config --system mergetool.simulink.cmd \
'mywrapper "$BASE" "$LOCAL" "$REMOTE" "$MERGED"'
% cat > mywrapper <<'EOF'
set -eu
s="${0##*/}"
b="${1:?}"
l="${2:?}"
r="${3:?}"
m="${4:?}"
wc=$(mktemp -d "$TMPDIR/$s-XXXXX")
trap "rm -rf '$wc'" INT TERM EXIT
ln -s "$b" "$wc/base.mdl"
ln -s "$l" "$wc/local.mdl"
ln -s "$r" "$wc/remote.mdl"
ln -s "$m" "$wc/merged.mdl"
$tool \
-base "$wc/base.mdl" \
-local "$wc/local.mdl" \
-remote "$wc/remote.mdl" \
-merged "$wc/merged.mdl"'
EOF
depending on details of your mergetool's operation you may need to
add `cp "$wc/merged.mdl" "$m"` at the end of the wrapper.
