MySQL++

mysql++-3.2.3.tar.gz contains a symlink: ltmain.sh -> /usr/share/libtool/config/ltmain.sh

However, on at least Ubuntu 17.10, there's no such file. ltmain.sh can be found at /usr/share/libtool/build-aux/ltmain.sh

Running configure reports (at the end):

sed: can't read ../ltmain.sh: No such file or directory
sed: can't read libtoolT: No such file or directory

Fixed by [ce2fefae8a]. Tarballs won't be re-generated, as this only shows up on systems quite different from the normal GNU type system, so it's a rare occurrence, but it will show up in the next release.
