The latest version of binutils, 2.27, added in commit
b700157db4, fails to build on systems
that don't have makeinfo installed. This commit therefore applies the
same fixup as the one used for binutils 2.26, which consists in
touching all the .info files, so that they don't get rebuilt.

binutils-arc-2016.09-eng008 build fails sometimes.
This happens due to the following issue:
binutils configure script has CC variable that stores compiler for
target and CC_FOR_BUILD variable that stores compiler for host.
WARN_FLAGS are verified by the script to be compatible only with CC
compiler but not with CC_FOR_BUILD compiler. Despite this WARN_FLAGS
are passed to both CC and CC_FOR_BUILD compilers. This leads to
unevident errors when cross-compiling. More information you can find
in the binutils mailing list:
https://sourceware.org/ml/binutils/2016-08/msg00117.html
We are going to write a patch for bunutils that fixes the initial
issue. Current patch contains temporary workaround. It should be
deleted after real fix.

this commit continues a series of updates of ARC tools.
This time we're updating tools to arc-2016.09-eng008.
Main updates were made for gcc. It was switched to GCC 6 and to
OSABI v4.
Besides this patch fixes buildroot ARC failures connected to
"crtbeginT.o" object file missing. This issue lead to two main errors:
1) "crtbeginT.o: No such file or directory", e. g. bootutils-1.0.0.
No comments are required here I hope.
2) Errors like "compiler cannot create executables", e.g.:
a) host-gcc-final-arc-2016.09-eng007 static build,
b) aespipe-2.4c.
That was caused because the test to determine if compiler is able to
create executables was failing due to missing "crtbeginT.o" file.

couple of fixes on top of it that will all make its way in the

We hope this patch will cure most buildroot ARC failures as it

So that should prevent breakage of many packages. As ARC now
supports PIE we remove ARC from BR2_TOOLCHAIN_SUPPORTS_PIE
exclusion in toolchain/Config.in file.
2) Assembler fix. This patch also have changes that fixes frequent

With this commit we're starting a series of updates of ARC tools.
Significantly rewritten arc-2016.03 tools introduced way too many
problems highlighted by Buildroot autobuilder. Now in attempt to
resolve as many issues as possible by the time final release of
arc-2016.09 tools is cut we'll be executing arc-2016.09 series
with engineering snapshots like this one.
We decided to go this way instead of applying separate patches here
and there because ongoing development introduces quite a lot of
changes and separate patches are not practical in Buildroot.
Moreover this will give us very clean visibility of number of
issues we see (hopefully it will decrease over time).
One of the important changes introduced in this engineering build
is initial set of changes for proper support of PIE on ARC in terms
of both building on host and running on ARC target. I expect some
PIE-related build breakages to go away and new ones will be treated
as the high-priority issues to be fixed ASAP.
For now we only update Binutils and GCC while keeping GDB
as it is of arc-2016.03 release because there're some issues
we'd like to resolve before releasing it to wider audience.
So again note this is one of the first engineering builds of
arc-2016.09 series and it might have all kinds of breakages,
please don't use it for production builds.

binutils got disabled as a target package for aarch64 back in Buildroot
2012.11 (commit 660d16f4).
The default version 2.21.1 at the time didn't really support aarch64, as
shown by the autobuilder error reference in that commit.
binutils has now had support for aarch64 since 2.23, but was never
re-enabled for aarch64.
All of the binutils versions currently supported by Buildroot (oldest
being 2.24) support aarch64, so we can now enable it without any
restrictions.
This same patch also touches the dropwatch, lightning and oprofile
packages which all select binutils and had the 'depends on !aarch64' to
keep Kconfig consistent. They are now re-enabled for aarch64 as well.
They are changed in this same patch so that Kconfig is kept consistent
and doesn't end up having them disabled in a commit which only has the
binutils change applied.
lightning has other explicit arch dependencies so it is not actually yet
available in aarch64, but at least the dependency on !aarch64 because of
binutils is not needed anymore.
Everything has been build tested with Buildroot and external toolchains.
binutils and dropwatch work fine in a qemu target. oprofile doesn't seem
to be supported in the qemu aarch64 processor but builds fine and seems
to have some level of aarch64 support in the source, so there doesn't
seem to be a reason to keep it disabled in Kconfig.

Build failed when "makeinfo" was missing on the build host.
This was happening because "makeinfo" is required to build .info targets
and make exited with error. The issue hadn't appeared before as there was
prebuilt documentation in ARC binutils tarballs, so no attempts had been
made to build docs.
Missing "makeinfo" only stops us from building docs
("missing" script already throws a warning on that regard).
Let's continue to build other targets.
Now exit code of the script called "missing" is checked.
The value 127 means that "makeinfo" is not available on the build host.
So when such value occurs, 0 is returned to the top level makefile.
Documentation is not being built but further build of binutils continues.

It turned out one of the previous fixes (required to build Linux
kernel)
------------------>8-------------------
ARC Binutils: a65b844aed
Buildroot: http://git.buildroot.net/buildroot/commit/?id=2d4e2e238a0ea9395152ae71d882d79b1f35094c
------------------>8-------------------
broke building of some other software packages.
In particular perf built for ARCv2 had corrupted .plt entries that lead
to immediate crash on perf execution.
That's an example of normal .plt entries:
------------------>8-------------------
< 1-st PLT entry >:
12c24: 30 27 8c 7f 0d 00 74 95 ld r12,[pcl,0x000d9574]
12c2c: 21 20 00 03 j.d [r12]
12c30: 0a 24 c0 1f mov r12,pcl
< 2-nd PLT entry >:
12c34: 30 27 8c 7f 0d 00 68 95 ld r12,[pcl,0x000d9568]
12c3c: 21 20 00 03 j.d [r12]
12c40: 0a 24 c0 1f mov r12,pcl
------------------>8-------------------
Note right after jump in its delay-slot r12 gets set with current value
of program counter. This is required for the first symbol resolution,
see implementation of _dl_linux_resolve here:
http://git.uclibc.org/uClibc/tree/ldso/ldso/arc/resolve.S#n46
And that's what we got in .plt after mentioned fixes:
------------------>8-------------------
< 1-st PLT entry>:
13384: 30 27 8c 7f 0f 00 84 75 ld r12,[pcl,0x000f7584]
1338c: 21 20 00 03 j.d [r12]
< 2-nd PLT entry>:
13390: 30 27 8c 7f 0f 00 78 75 ld r12,[pcl,0x000f7578]
13398: 21 20 00 03 j.d [r12]
------------------>8-------------------
Note r12 setup is missing.
That happened because linker thought the size of PLT entry is 12 bytes
(which is exactly the size of PLT entry for ARCv1, read ARC750/770)
while for ARCv2 PLT entry is 16-bytes long. And erroneously trailing 4
bytes were truncated.
Current commit fixes this misbehavior and PLT gets generated properly
again.
Now we have a fix for that issue, see
5df50c6108
This fix is in arc-2.23-dev branch and will be a part of the next
release of ARC tools, so then this patch must be removed from buildroot.

With the fix for missing .tdata/.tbss sections we unintentionally
introduced a regression for ARCv2 ISA (read ARC HS38) kernel building.
That's what we got on attempt to build kernel:
----------------------------------->8--------------------------------------
LD drivers/video/fbdev/built-in.o
arc-linux-ld: ERROR: Attempting to link drivers/video/fbdev/omap2/built-in.o with a binary drivers/video/fbdev/built-in.o of different architecture
arc-linux-ld: failed to merge target specific data of file drivers/video/fbdev/omap2/built-in.o
scripts/Makefile.build:337: recipe for target 'drivers/video/fbdev/built-in.o' failed
make[3]: *** [drivers/video/fbdev/built-in.o] Error 1
scripts/Makefile.build:403: recipe for target 'drivers/video/fbdev' failed
make[2]: *** [drivers/video/fbdev] Error 2
scripts/Makefile.build:403: recipe for target 'drivers/video' failed
make[1]: *** [drivers/video] Error 2
Makefile:944: recipe for target 'drivers' failed
make: *** [drivers] Error 2
----------------------------------->8--------------------------------------
The reason was empty .tdata and .tbss sections in empty archives. And
later empty archives were linked in built-in.o with default architecture
(in our case ARCv1 ISA, read for ARC 700) and then expected failure
happened when objets for different architectures were attempted to link
together.
Now we have a fix for that issue, see
a65b844aed
This fix is in arc-2.23-dev branch and will be a part of the next
release of ARC tools, so then this patch must be removed from buildroot.

Two patches below are taken from development branch of ARC binutils,
so one the next release of ARC tools happens both patches must be removed.
These 2 patches:
0003-ld-arc-Provide-the-.tdata-symbol.patch
0004-Provide-.tbss-symbol.patch
fix missing .tbss and .tdata sections during linkage stage such as:
------------------------------>8---------------------------
arc-linux-g++ test.cpp
../arc-buildroot-linux-uclibc/lib/libstdc++.so: undefined reference to '.tbss'
collect2: error: ld returned 1 exit status

Rename the binutils configuration option to match that one used by gcc
where the patchlevel is explicitly left out.
