Can I use make conditionals with elif too?

I can do simple checks with make's conditionals, like that:

var = yes
ifeq $(var) "yes"; then
    echo "yes"
else
    echo "no"
fi

But the docs say nothing about elif. Can I do it like the following ?

var = yes
ifeq $(var) "yes"; then
    echo "yes"
elifeq $(var) "no"; then
    echo "no"
else
    echo "invalid"
fi

If not, is that possible at all, or do I have to make nested conditions or use test ?
