I've just been through a very similar exercise on CentOS 6, not for samba, but involving gnutls. My respect for those who manage to build gnutls at all has grown considerably. The code below works for my purposes.
In the p11-kit section, consider that your system does have systemd. In the libtasn1 section, I'm applying a patch that changes the perlesque C99 for loops into something gcc 4.4.7 can digest. I don't know if gcc 4.8.5 knows C99 (probably not). If you know a little C you can easily figure out what to do if needed. I didn't investigate building gnutls without external libtasn1 etc.
Now, linking your code against this version of gnutls is also a fun exercise. You need to configure against the same --prefix, for starters. You may also require the same PKG_CONFIG_PATH= stanza as below for gnutls. In your Makefiles, you may need to change anything "-lgnutls" to "-lgnutls -lgmp -ltasn1".
