Use $(TEXI2DVI) just once, no separate texindex.

You seem to be lacking the treelang.generated-manpages target.  It should
be there, though it needn't do anything.

diff_excludes is obsolete.  When maintaining a front end outside the tree
for a long time, you need to watch gcc-patches for patches relevant to it
(in this case, mine removing all the relics of diff_excludes from all
front ends) and update yours accordingly.

Make-lang.in and config-lang.in are documented in sourcebuild.texi.  If
you haven't read the documentation of the front end build interface, then
do so, and update the front end accordingly.

(For a toy language like this, some of the list of places outside a front 
end directory that need updating for a new front end may not apply.  
However, you should go through them, and, for each one you're not 
updating, send the justification to gcc-patches.)
