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.]

Now when new shiny tools are released by Synopsys we're ready for
version update in Buildroot again.
More details about arc-2014.12 release are available here:
https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/tag/arc-2014.12
Following patches were removed from GCC since they are a part of release
now:
* 200-size_type_unsigned_int.patch
* 300-ptrdiff_type_int.patch
* 400-call-arc_hazard-before-branch-shortening.patch
* 401-fix-length-attribute-for-casesi_load-pattern.patch
* 402-fix-length-of-instructions-that-are-in-delay-slot-and-needs-to-be-predicated.patch
* 403-update-casesi_compact_jump-instruction-length.patch
But since arc-2014.12 tools are still based on GCC 4.8 following patches
ar still relevant so moving to the new folder to match ARC gcc bump.
* 100-libstdcxx-uclibc-c99.patch
* 910-gcc-poison-system-directories.patch
Binutils are still based on 2.23 so following patch still makes sense:
* 600-poison-system-directories.patch

2.22 is getting quite old (Nov 2011) and we've recently added 2.25. 2.24 has
been used for the "new" architectures for a while and there's no known
issues going to 2.24 for the rest, so bump the default version.

Now when new shiny tools are released by Synopsys we're ready for version
update in Buildroot.
Important change in this release is switching to combined "binutils-gdb" repo
in accordance to upstream move.
Following patch now is a part of the most recent relese:

So dropping it.
package/binutils/arc-4.8-R3/0001-arc-Honor-DESTDIR-in-custom-Makefile.patch
Since arc-2014.08 tools are still based on GCC 4.8 following patch is still
relevant so moving to the new folder to matxh ARC gcc bump.

After the following commits:

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.

- 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.

* Move cross/host gcc to HOST_DIR
