toolchain/arc: update to the most recent release arc-2016.09

2017-05-02T13:17:30Z

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: [1] https://patchwork.ozlabs.org/patch/726686/ [2] https://patchwork.ozlabs.org/patch/726687/ Signed-off-by: Alexey Brodkin

toolchain: unbreak glibc on MIPS

2017-02-27T11:15:45Z

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 [ 0.920077] Kernel panic - not syncing: Attempted to kill init! exitcode=0x00007f00 [ 0.920077] [ 0.929450] Rebooting in 1 seconds..

toolchain/uclibc: Bump version to 1.0.22

2017-02-11T14:38:39Z

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. [1] http://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng.git/commit/?id=29ff9055c80efe77a7130767a9fcb3ab8c67e8ce Signed-off-by: Alexey Brodkin

toolchain/uclibc: Fix unmanned configuration with "V=s"

2017-02-11T14:38:32Z

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 :) Signed-off-by: Alexey Brodkin
