If two keys are cross signed, then the same person (probably)
controlled them both. In this case, don't raise a TOFU conflict.
This usually occurs when someone transitions to a new key. When that
person rotates to a third key, she will typically only cross sign it
with the second key. As such, we check this transitively to avoid
declaring a conflict between the 1st and 3rd key.
* g10/sig-check.c (check_signature2): Replace arg PK by R_PK and
change the semantics. Also clear the other R_ args on function entry,
use gpg_error() and change retturn type to gpg_error_t.
* g10/mainproc.c (do_check_sig): Add arg R_PK.
(list_node): Pass NULL for new arg.
(check_sig_and_print): Rework to make use of the returned PK.

The output
gpg: textmode signature, digest algorithm SHA256, key algorithm rsa2048
showed the pubkey algo of the primary key which was surprising.
Changed to print the algo of the subkey used for verification.
