arc-2016.09 is the most recent toolchain for ARC cores and
it is based on top of upstream Binutils 2.27 and GCC 6.2.1.
With updated major version of GCC we copied all GCC 6.x patches
for ARC as well as Bintils 2.27 patches.
Note that toochain sports ARCv4 ABI and so must be used
with 4.8+ Linux kernels. Even though it will build v4.4 kernel
perfectly fine on attempt to run user-space apps they won't
work with older kernel. That said previuosly sent RFC patches with
Linux kernel update are required:

Binutils recently updated the ABI version to 5, which broke glibc, as it
refuses to load anything > 3. Upstream reverted the ABI version update,
so backport the commit.
Fixes the following error on boot:
/bin/sh: error while loading shared libraries: /lib/libcrypt.so.1: ELF file ABI version invalid

Important change was made in 1.0.18: all sub-libs were merged
in one and only libc similarly to musl.
See [1] for more details.
To support that we had to remove refences to those sub-libs like
libpthread, libcrypt, libdl, libm, libutil etc.

Currently on attempt to configure uClibc with "V=s" user is prompted
to answer on configuration questions. Major inconvenience here is
build procedure get paused until user answers all questions.
That happens because not all symbols are defined in our .config.
Solution is as simple as usage of "olddefconfig" target instead of
simple "oldconfig". In that case default values get silently set
for symbols not defined by our .config explicitly.
We haven't noticed that subtle issue before because without "V=s"
what we do is "make oldconfig < /dev/null" which automatically
answers all questions :)

If the staging dir was deleted, the build needs to recompile some files.
This change speeds up this corner case significantly

Use 2.27 as default which is the current relese.
Makes it easier to get support and submit patches upstream if needed.

This reverts commit dde5c729ec.
The uClibc update was completely untested, does not build with Kernel 4.4 and
did not adjust the configuration to predeclare new config symbols.

This patch updates musl to 1.1.16+ [0] and removes all the
backported patches. This is a major release and tagged as such.
For more information visit musl-libc.org or read the WHATSNEW.
Furthermore, this patch also changes musl to download directly
from git. This makes it easier to update musl in the future.
The patch custom Add-format-attribute-to-some-function-declarations.patch
was assigned a new 400- number. This should avoid confusion
since 0xx numbers are usually assigned to backports.

This is intended to be used for a wide array of package sanity checks.
The first check that is implemented is for the hash of downloaded files.
It checks:
- Missing hash
- Use of SHA256 instead of MD5
- dl/<file> hash not matching hash in makefile
- deprecated MD5SUM variable
The deprecated MD5SUM variable check is skipped for feeds/ until OpenWrt
is updated as well

Make it a choice menu which offers the 3 C libraries we know about: glibc,
uClibc and musl. While at it, make it possible for the external toolchain libc
to select USE_GLIBC, USE_UCLIBC or USE_MUSL which is used by several packages
to conditionally include specific CFLAGS (e.g: iproute2).
Because USE_GLIBC et al. can now be selected by external toolchains, we need to
restrict the per-libc menus to check on !EXTERNAL_TOOLCHAIN.
While at it, make musl the default C library for external toolchain to match
the internal toolchain.

Configurations without shadow passwords have been broken since the removal
of telnet: as the default entry in /etc/passwd is not empty (but rather
unset), there will be no way to log onto such a system by default. As
disabling shadow passwords is not useful anyways, remove this configuration
option.
The config symbol is kept (for a while), as packages from feeds depend on
it.
