I didn't bother, because I didn't think any part of the change should be applied 
to emacs-24.  As you mentioned, an 'info' dir shouldn't go missing with any 
normal use of an Emacs distribution tarball.  The Debian build process is quite 
specialized and surely the Debian folks can get it to work themselves, e.g., by 
doing a "mkdir info" after the "make bootstrap-clean" (or better yet, omit the 
bootstrap-clean).

Ah, sorry, I was wrong about the wildcards.  I didn't know that GNU make 
expanded wildcards in prerequisites.  So that part of the change didn't fix any 
bugs (though the use of the 'wildcard' function is still helpful).  I have fixed 
the corresponding ChangeLog entry accordingly, in trunk bzr 118182.  That bzr 
also removes a couple of other calls to 'wildcard' that were present only 
because of the same misunderstanding of how wildcards work in prerequisites.
