package/binutils: add support for 2.42

Browse Source 
Note that the hash of the tarball does not need to be added, as it was
already added as part of commit 11b439ce1b
("package/binutils-bare-metal: new package").

Our existing 2 patches are simply rebased, with minor conflict
resolution required.

From d71fb5a9999ee7c8963342caa0d5cbb16872ab07 Mon Sep 17 00:00:00 2001
From: Romain Naour <romain.naour@gmail.com>
Date: Fri, 25 Dec 2015 11:38:13 +0100
Subject: [PATCH] sh-conf
Likewise, binutils has no idea about any of these new targets either, so we
fix that up too.. now we're able to actually build a real toolchain for
sh2a_nofpu- and other more ineptly named toolchains (and yes, there are more
inept targets than that one, really. Go look, I promise).

[Thomas: rebase on top of 2.29, in which sh64 support was removed.]
