8b5d644bb3 toolchain: add support of ARC architecture
This includes binutils, gcc, gdb and uClibc-ng.

Latest release of ARC gcc (as of today it is "arc-2015.06")
is based on upstream gcc 4.8.4.

Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/gcc

Latest release of ARC binutils (as of today it is "arc-2015.06")
is based on upstream binutils 2.23.

Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06

Latest release of ARC GDB (as of today this is "arc-2015.06-gdb")
is based on upstream gdb 7.9.1.

Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06-gdb

Note that for binutils and gdb that come from unified git repository
(which is the case for upstream binutils/gdb today) we need to disable
building of gdb in binutils and binutils in gdb hence in binutils:
------>8------
--disable-sim
--disable-gdb
------>8------

and in gdb:
------>8------
--disable-binutils
--disable-ld
--disable-gas
------>8------

Also in gdb we disable sim because if the following breakage while
building with it:
------------>8------------
/usr/bin/env bash ./../common/genmloop.sh -shell /usr/bin/env bash \
        -mono -fast -pbb -switch sem5-switch.c \
        -cpu a5f -infile ./mloop5.in \
        -outfile-suffix 5
unknown option: bash
Makefile:699: recipe for target 'stamp-5mloop' failed
make[7]: *** [stamp-5mloop] Error 1
------------>8------------

57a70e8a64 toolchain/uClibc: add support of uClibc-ng
uClibc-ng is a spin-off of original uClibc, see http://www.uclibc-ng.org/

We try to regularly add changes from uClibc to uClibc-ng.
We even sent patches and bug reports to the uClibc mailing list.
The config file is compatible between uClibc-ng 1.0 and uClibc git master.
This might change in the future.

Our main goal is to provide regularly a stable and tested release
to make embedded system developers happy.

The main advantage of uClibc-ng over olde good uClibc is regular releases
so there's no need to keep tons of patches on top of years old
0.9.33.2

Build-tested for
 [1] ARM: Sunxi generic
 [2] MIPS: Netgear WNDR3600/3700/3800

Run-tested for [yet out of the tree] Synopsys Designware ARC AXS101.

491f3fc048 Support for building an hardened OpenWRT
Introduce configuration options to build an "hardened" OpenWRT.

Options to enable Stack-Smashing Protection, FORTIFY_SOURCE and RELRO
have been introduced.

uClibc makefile now automatically detects if SSP support is necessary.

hostapd makefile has been fixed to use "^" as sed separator since
using a comma was problematic when using "-Wl,-z,now" and the like in
TARGET_CFLAGS.

Currently enabling SSP on user space depends on enabling SSP kernel
side, this is due to the fact that TARGET_CFLAGS are used to build
kernel modules (at least). Suggestions on how to avoid this are welcome.
Using "select" instead of "depends on" doesn't seem to work with choice
entries.

Tested with a lantiq (WBMR) router, GCC 4.8, uClibc and a subset of
the available packages.
Needs to be tested with GCC 4.9 and the remaining packages.
PIE not currently included.

750115a65c toolchain/uClibc: Disable mips16 for uClibc for now
For now, build uclibc without -mips16. There's no mips16 syscall
support AFAIK and uclibc uses inline assembly syscalls a lot.

In addition, touching errno means touching a TLS model symbol, and
that's not supported in gcc 4.6.

The __set_errno macro can be put back to calling
errno_location(). This allows much of the library to be built in
mips16 mode. I don't understand the implications to the thread library
of doing this.

A list of "build as -mno-mips16" C source files can be placed in the
mips architecture-dependent build files. Maintaining the list would be
no fun.
