gnutls28 transition

[Dimitri John Ledkov]

Hello all,

gmp has been recently re-licensed and all architectures and ports have
the updated gmp in jessie/sid. Well, all but powerpcspe & x32 both of
which recently have negative slope on their build status graphs.
Thus GPLv2 and LGPLv3 compatible software packages can link against gnutls28.

Should we start transition to gnutls28 by default, for all packages
that are compatible?

Can powerpcspe & x32 porters try to get latest gmp built?
