Turns out my reasoning was correct (thanks Brandon, for keeping me pointed in
the right direction!) but I just forgot to make a target for the file that
depended on it.

This target always needs to be built, so I add this line:
ADD_CUSTOM_TARGET(info ALL DEPENDS chicken.info)

This means the 'info' target _always_ gets built whenever something's built.
It doesn't build too much, because it doesn't actually do anything if its
dependencies are up to date.

It also means you can now invoke 'make info' to build the info files.  Typing
'make chicken.info' results in "don't know how to make target chicken.info".
Which is kinda logical if you consider that targets != files, I guess :)

The final patch for chicken.info is attached.

Cheers,
Peter
