   Unfortunately, there is no way to make an index entry refer to another 
   one like this.

That isn't really right, @deffnx is the right way of doing this, and
then one can use @anchor to define the reference.

  @deffn Function adjoin
  @deffnx Function adjugate
  @anchor{Definition of adjoin}
  @anchor{Definition of adjugate}
  Frobnicate the adjugation by doing an adjoin on the frob.
  @end deffn
  
  @xref{Definition of frob} for awesomeness.

You could also do "@deffn .. adjugate", followed by a @xref{Defintion
of adjoin}, but that is kinda ugly.
