It finally worked fine using a shortcut in ~/.ssh/config by adding to
setting:

(add-to-list 'tramp-connection-properties
             (list (regexp-quote "zte") "remote-shell" "sh"))

Where "zte" is the ssh shortcut.

Probably you should mention in documentation that the shortcut have to
be added there in addition of the real url of host.

I will look ASAP if I can make it working with another server like
dropbear.

Thanks.
