doctest rtems example

[Chris Johns]

Hi Sam,

Thanks for the post. The website for the code is:

https://github.com/doctest/doctest

I have been using this and I can port tests between Linux and RTEMS. I like it
because it works and it is a single header. There is no need to build and link
libraries.
