Just for the record after some time of diving into things and thinking about
it: here a nice and sweet solution - without anything like diff wrappers or
evil hackery in the autotest scripts - which imply changes the diff command
in the shell environment:
set -a
diff_cmd="$(command -v diff)"
function diff () { "$diff_cmd" --strip-trailing-cr $@ ; }
set +a
make check
unset -f diff # clean-up
Thanks,
J.
