Yes, you need lemon.  It generates the display filter grammar.

I think I may have (finally, after several wrong turns) figured out 
what's wrong with cross-compilation: we're not calling 
AC_CANONICAL_TARGET any more (this was commented out in rev 25232).

Just un-commenting it breaks things, so can you try to see if it works 
with configure.in starting like this:

(In 1.2 the revision and version numbers will be different.  What's 
important is that AC_INIT comes first, then AC_CANONICAL_TARGET, then 
AM_INIT_AUTOMAKE.)
