Testing a GDB plugin in travis-ci.org

Hello,

I recently had some folks contribute code to support ARM targets to an
open source GDB plugin (written in Python) that I maintain. While
re-working the contribution, I added basic support for testing the ARM
functionality in the travis-ci.org continuous integration environment.
I wasn't able to find any guidance for doing this, so I wrote a blog
post to capture some of what I learned along the way:

Just an FYI -- I thought some folks might find this useful (I would
have). Many apologies to anyone that might consider this noise.
