[OE-core] [PATCH] nettle: clean up license information

[Jussi Kukkonen]

Hi,

I realise I'm a bit late (with the commit in master already) but I'm
looking at upgrading this recipe and had some questions on this patch
and the recipe in general.

I think this is wrong, whichever version you look at -- our current
version is just "LGPLv2.1+", the current upstream release is "LGPLv3+
| GPLv2+"

I'm going to send a patch upgrading the recipe to the current upstream
release (and setting license to "LGPLv3+ | GPLv2+"): it might seem
like this makes gnutls effectively LGPLv3 but that actually happened
last year with the gmp upgrade. Comments on this welcome.

>From the reference I had the impression this "LICENSE_something"
construct would imply there is a package "something". But the nettle
recipe does not produce "nettle-cast" or any of these. What is the
purpose here?

Thanks,
 Jussi
