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

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.

In buildroot we maintain a couple off-the-tree patches.
In particular for binutils and gcc packages.
Because we have many versions of mentioned packages patches for each
particular version reside in a folder which name matches full version
name of the package.
For example we used to have patches for binutils distributed as part of
arc-2014.12 tools in folder ""package/binutils/arc-2014.12". Now with
bump of ARC tools version we need to rename folder with patches to
"arc-2015.06-rc1".
The same applies to gcc.
Should fix http://autobuild.buildroot.net/results/2b2/2b27a4a64c0b225ae479ecfccf7a97f5ea95598c/
As discussed before it's not possible to reproduce reported problem on recent
Fedora 21/22 distros (at least we know about them) but I may confirm that
patches were applied fine and everything was built well. Hopefully reported
build failure goes away now.

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.

Even though this is only RC1 it's been heavily used internally so it should
not be any worse than existing arc-2014.12.
Moreover this relase (and so its RC1) finally delivers support of NPTL
for ARC in uClibc.
That's why it would be good to allow interested users to start trying it
(for example WebKit and apps that use WebKit could be successfully built
and run) also it will be helpful to run that new toolchain through
autobuilder in attempt to find any hidden regressions so we have a solid
toolchain for release.
If there's an interest in that patch more patches will follow with
subsequent RCs and essentially on appearence or relese Buildroot will be
updated with it.

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.]

If Binutils and/or GDB are fetched from the unified binutils-gdb
repository, then the tarball will contain both Binutils and GDB
sources, unlike the "normal" tarballs that contain only the titular
package. To keep packages separated in Buildroot we need to disable
undesired components when configuring.
Binutils and GDB migrated to a common Git repository in the October
2013 [1]. Previous Git repositories were incomplete copies of CVS
repository which copied only the relevant files (no binutils files in
GDB, and vice versa). In the new binutils-gdb repository there is no
such separation and a result all files exist in directory after
checkout. So if "configure" and "make" are used without explicit
targets, all projects will be built: binutils, ld, gas, bfd, opcodes,
gdb, etc. In case of Buildroot this would mean that selecting Binutils
only, still will build both Binutils and GDB. And if GDB is selected
as well, then both packages will be built two times, and Binutils from
GDB directory will overwrite initial build of Binutils (or vice versa
if Binutils will be built after the GDB). This is a serious problem,
because binutils and GDB use separate branches in this common
repository. In case of Buildroot this means that separate Git commits
(or tags) should be used when downloading source from Git.
This affects only Git repositories, because GNU release tarballs still
contain only relevant packages.
This change is backward compatible, because if "normal" tarball is
used (without extra directories), than --disable-* configure options
are just ignored by configure.

After the following commits:
26974bf6a7 use default binutils for sh architecture
6f1cf344d9 binutils: Use the default version by default on MIPS
the 2.21.1 binutils version is no longer required, and since it's an
old version, we get rid of it.

Following d4839ffcab ("binutils: remove
2.20.1, 2.21 and 2.23.1"), Config.in.host contains unneeded
definitions of BR2_BINUTILS_VERSION for no longer existing
versions. This patch fixes that.

This fixes the following build error reproducible with any linux kernel
module built with a recent buildroot toolchain:

- The 2.20.x series is old, it no longer makes sense to support it.
- In the 2.21.x series, we still have 2.21.1, so keeping 2.21 doesn't
make much sense, so this patch removes it.
- Similarly for the 2.23.x series, having both 2.23.1 and 2.23.2
doesn't make much sense, so this patch removes 2.23.1 and keeps
2.23.2.
