more web failure with external_binary

[Graham Percival]

John, could you please test web with EXTERNAL_BINARY?

>From a clean checkout of the source code and using 2.11.40 (ie using
the current lilypond-book), I get this:

...
/Users/gperciva/usr/src/lilypond/Documentation/user/out-www//templates.texi:1374:

and out-www/  only contains .html files for the -big-page.  I'm guessing
that the learning manual fails to create info images, and that stops
the build halfway through.

Cheers,
