Good question. The AMS files don't seem to have it (the symbol is
hardly used by mathematicians). But revtex4 defines it (for latex), in
/usr/local/texlive/2013/texmf-dist/tex/latex/revtex4/revsymb.sty
An example of using it:
\documentclass{revtex4-1}
\begin{document}
$\lambdabar$
\end{document}

I have put that in and ran 'context --make' pending the font update.

I'll do that. If you know of it, could you point me to their bug tracker
(or best way to file a bug report)? I roamed the GUST site without
finding it.

That seems to be what revtex does (it has quite a complicated
definition).
