A simple way to do this is to use the GMSL seq (string equal function)
and then do

$(if $(call seq,LHS,RHS),THEN,ELSE)

Of course you cannot wrap this in a $(call) because THEN and ELSE will
be expanded and if you have any side effects ($(warning), $(error),
$(info), $(shell), $(eval)) in them then that would be undesirable.  If
not then

    if-eq = $(if $(call seq,$1,$2),$3,$4)

should work fine.
