I don't think there would be plans to do such a backport now so closing.

Title:
gnutls26 does not accept out of order certificate chains, whilst
gnutls28 & openssl do
Status in gnutls26 package in Ubuntu:
Won't Fix
Bug description:
gnutls fails to connect to https://01.org in trusty
In the certificate chain the top level certficate is trusted and is in
/etc/ssl/certs/ca-certificates.crt, and gnutls-cli (3.x based) in
utopic and openssl connect to 01.org just fine.
gnutls-cli (2.6 based) in trusty does not.
Good:

Bad:
gnutls-cli -V --x509cafile /etc/ssl/certs/ca-certificates.crt 01.org
Processed 164 CA certificate(s).
Resolving '01.org'...
Connecting to '198.145.11.105:443'...
*** Verifying server certificate failed...
*** Fatal error: Error in the certificate.
*** Handshake has failed
GnuTLS error: Error in the certificate.
Thus anything that talks to 01.org over https using gnutls (e.g. git with
libcur(gnutls)) fails to verify certificates and thus does not work in Trusty.
