examples-v2 with waf

[Gedare Bloom]

Hello,
GCI students, Chris Johns, and myself have made it possible to compile
the examples-v2 git repository using waf. Please have a look at:
https://github.com/gedare/examples-v2/tree/waf

This effort is in parallel to the traditional RTEMS Makefiles, which
can still be used with examples-v2. If there are no issues I will push
these changes to the upstream examples-v2 on git.rtems.org in the next
week or so.
