[Buildroot] [PATCH 2/2] toolchain/arc: use gcc/binutils with tls support for uclibc-ng

[Waldemar Brodkorb <wbx@openadk.org>]

uclibc-ng includes support for NPTL for arc from:
https://github.com/foss-for-synopsys-dwc-arc-processors/uClibc

Special branches for gcc and binutils are required to
provide the needed TLS support in the toolchain.
