In my experience, "EBNF" and "LL"/"SLR"/"LALR" are widely known (they
are "classic compiler terms"), for the type of person who might be
interested in parser generators, but "GLR" isn't.
So I'd provide an expansion (maybe in parentheses) for the latter only.
Moreover, one wants to err on the side of being too verbose, at least
in the long description; of course one should provide both the acronym
and the expansion in case the person only recognizes the former
[e.g. "XYZ (Xxx Yyyy Zzzz)"].
