In Gnus, when sending a GnuPG-signed message the signing operation is
executed twice if the message has gcc field for storing local copy. It
seems that the background "gpg --detach-sign" process is executed once
for the outgoing message and once for the local copy (gcc).
It's a small annoyance (and first a surprise) when using external
OpenPGP smartcard for the secret-key operation. My Yubikey smartcard has
to be touched before secret key operation is allowed. Some other
smartcards require pin code on physical machine.
Would a single sign operation suffice in Gnus? After all, it's just two
copies of the same message?

Indeed. But, man, was this difficult to debug, because putting a
`debug' statement into any of the mml functions just didn't work. It
turns out you had to say
(let ((inhibit-redisplay nil))
(debug))
to get it to debug. (I've now amended the doc string.)
So that took like nine hours, and it turns out that (logically enough)
the second call to the encoding function is done from
`gnus-inews-do-gcc'. It doesn't really know anything about what may
have happened before -- it just interprets the Gcc header, and then
calls `message-encode-message-body', which will encode the data again.
So to avoid the double encoding, Message needs some way to tell this
function not do to that, but instead cache the encoded value and make
`gnus-inews-do-gcc' use that instead. Hm... Perhaps a buffer-local
variable will do the trick...
I think I'll have a look at that tomorrow.
