[OE-core] [PATCH] elfutils: remove Elfutils-Exception and include GPLv2 for shared libraries

[Mikko Rapeli]

Elfutils-Exception no longer exists after upstream release 0.154
and commit:

commit de2ed97f33139af5c7a0811e4ec66fc896a13cf2
Author: Mark Wielaard <mjw at redhat.com>
Date:   Tue Jun 5 17:15:16 2012 +0200

NEWS file in the sources says this about switch from GPLv2 to
GPLv3 license:

https://sourceware.org/git/?p=elfutils.git;a=blob;f=NEWS;h=5a06047f255e3c9a63828953759fd18a4ba9a3f3;hb=HEAD#l362

 362 The license is now GPLv2/LGPLv3+ for the libraries and GPLv3+ for stand-alone
 363 programs. There is now also a formal CONTRIBUTING document describing how to
 364 submit patches.

libasm, libdw and libelf are thus covered optionally by GPLv2 license.
