that the target variant, when no host variant is built, was still

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 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.

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.

Following commit 36555b4c8d ("ARC:
switch to RC1 of upcoming arc-2015.06 tools"), the binutils package
only contains the hash information for the 2015.06-rc1 ARC version of
binutils (which is in fact no hash). However, when an external
toolchain is used, and binutils is built for the target, it's still
the old 2014.11 binutils version that gets used in binutils.mk,
causing a build failure because there is no hash available for this
version.
This commit fixes that by using 2015.06-rc1 as the default binutils
version on ARC, which is used when no host-binutils has been built.

Add a new option BR2_GCC_ENABLE_LTO that builds gcc and binutils with
LTO support.
Individual packages still have to enable LTO explicitly by passing '-flto' to
GCC, which passes it on to the linker. This option does not add that flag
globally. Some packages detect if the compiler supports LTO and enable the flag
if it does.
To support LTO, ar and ranlib must be called with an argument which triggers the
usage of the LTO plugin. Since GCC doesn't call these tools itself, it instead
provides wrappers for ar and ranlib that pass the LTO arguments. This way
existing Makefiles don't need to be changed for LTO support. However, these
wrappers are called <tuple>-gcc-ar which matches the pattern to link to the
buildroot wrapper in the external toolchain logic. So the external toolchain
logic is updated to provide the correct symlink.
[Thomas:
- Add a separate BR2_BINUTILS_ENABLE_LTO option to enable LTO
support in binutils. This is a blind option, selected by
BR2_GCC_ENABLE_LTO. It just avoids having binutils.mk poke
directly into gcc Config.in options.
- Remove the check on the AVR32 special gcc version, which we don't
support anymore.
- Adapt the help text of the LTO Config.in option to no longer
mention "Since version 4.5", since we only support gcc >= 4.5 in
Buildroot anyway.
- Fix typo in toolchain-external.mk comment.]
