[PATCH] [RSB] Add support for building Epiphany tools

[Hesham ALMatary]

This patch adds support for building Epiphany tools. Currently some tools
are fetched from my repositories (until my pull requests get merged), and
other tools are fetched from Adapteva repositories. In the future, the
tools should be fetched from GNU upstreams when Adapteva folks push
their latest changes there.
