ARC: AXS10x - extras for Synopsys release

This adds extra options on top of Buildroot's existing configuration
for AXS10x boards.

Important changes:
 1. Linux kernel switched to arc-3.18-1 from SNPS GutHub
    This is required because support for ARC PGU is not upstreamed yet.

 2. Additional packages included:
    * GDB (both server and target gdb)
    * MPlayer
    * Dropbear
    * RT-tests
    * iperf3
    * perf

 3. Extra options fr toolchain to build above packages
    * C++
    * RPC
    * Wchar
    * Pthread debug
