The ifeq conditional was evaluated long before the make recipe is.  If
you want to have a conditional in a recipe that uses automatic
variables, use the $(if ...) function.  

For your use case, it may help to have a utility function to do the
string comparison.

$(targets):
        echo current target is $@
        echo $(if $(call eq,$@,sms),yep they are equal,nope they're not equal)

    --jtc
