* LINK> ( lfa -- cfa )

converts a pointer to the link-field (LFA) to point
then to the corresponding code-field (CFA)

BEWARE: this one does not care about SYNONYMs and it is the
only way to get at the data of a SYNONYM. Therefore, if you have
a synonym called A for an old word B then there is a different
result using "NAME>" on an A-nfa or using "N>LINK LINK>" since the
first "NAME>" will return the xt of B while the latter will return
the xt of A - but executing an xt of A is an error and it will THROW

this difference is intentional to allow knowledgable persons to
do weird things looking around in the dictionary. The forth standard
words will not give you much of a chance to get hold of the nfa of
a SYNONYM word anyway - asking FIND for a word A will return
the execution token of B immediatly and "NAME>" on that one lead to
the nfa of B and not that of A.
