This produces yet another different signature. I imagine I'm now hashing the hash and encrypting that.
I can't conveniently switch to giving gnutls_x509_privkey_sign_data() the entire original data blob to be signed as at this point in the code I no longer have it, but I do have the output of the hash of it.
