I didn't mean to drop the patch.  I just haven't had the time to test
the changes described below, not being too familiar with how binutils
distribution works yet.

I don't think it is right to do that; other code invokes $(MKDOC) and
for that the chew binary needs to be present in the user build tree.

My idea was to clean stamp-chew when $(MKDOC) was cleaned (i.e., in
MOSTLYCLEANFILES).  It should not be a problem if the texi files rules'
get triggered for the user of a tarball, because the generated files
should be identical.  Even if the rules for the info files get
triggered, they should not be a problem because of the 'missing' script.
But I'd really like to test this well before proposing a new patch.

Thanks,
Ralf
