Thomas Petazzoni 4210c49357 binutils: add patch to fix AArch64 glibc build issue
The autobuilders are not able to build glibc on AArch64 since we moved
to the internal toolchain backend as the default for AArch64. The
reason is that the cross-ld segfaults while linking of the glibc
utilities. Unfortunately, the issue has so far been impossible to
reproduce outside of the autobuilder CI loop itself: even on the same
machine, in the same chroot, the issue does not appear.

Today, Will Newton helped me analyze a bit further the problem. In the
logs of the build machine, we have found that the following segfault
notification matched the dates of the autobuilder failures:

See
http://autobuild.buildroot.org/?reason=glibc-2.18-svnr23787&arch=aarch64
for the autobuilder results.

So, the segfault always happens while accessing an address 2 bytes
after the beginning of a page: it looks like a buffer overflow, which
gets triggered because the object is placed towards the end of the
previous page, and crosses over the next, unallocated page.

Moreover, we looked at the 0x4caf80 address in an AArch64 cross-ld
built by Buildroot, and it turns out that it is part of the
iterative_hash() function. This nicely correlates with the patch that
Will Newton had pointed in
http://lists.busybox.net/pipermail/buildroot/2014-May/095881.html as a
fix for invalid memory accesses reported by Valgrind in the AArch64
cross-ld, specifically around the same area of 'ld'.

Therefore, even though we have not been able to reproduce the issue
outside of the autobuilders, and cannot confirm that the patch is
fixing the issue, I propose to integrate this binutils patch into
Buildroot. It is anyway an upstream binutils patch, which fixes a real
problem.

Rebuilding as.info with makeinfo version 5.2 results in a build error,
even with pristine binutils source. Dropping hunks that change *.texi*
files avoids documentation rebuild.

Arnout Vandecappelle fc82f8df85 binutils: add upstream patch to fix --enable-install-libiberty flag
Fixes http://autobuild.buildroot.org/results/1ea/1ea98985ce06dc1b7569ef5abe2fc13090fb5f3a

The upstream patch patches both configure.ac and configure, so we keep
that.

It is numbered 001 because it is an upstream patch, so it should come
before the buildroot patches.
