Why the change from "source_set" to "static_library"? I though that "source_set"
where recommended everywhere with gn. Is this required here?

[Dirk Pranke, 2015/07/31 21:27:40]

source_set is recommended, you're right.

I had initially changed this because the test_support library was pulling in
some files that we didn't need, and changing to a static lib works around that.

I'll go back and separate the files explicitly.
