This seems odd too. Why are lint_android_sdk_root and _version separate from the
android_sdk_root and _version that are configurable below?

[estevenson, 2016/08/30 16:43:51]

Because the defaults below can be set in other places and might not be
"//third_party/android_tools/sdk". I hardcoded it here instead so that we don't
need to make an additional downstream change. If you'd prefer, I can make the
downstream change and use the same pattern for defaults in this file.

I think I'd prefer a downstream change. Having a hard-coded lint path doesn't
seem like the right default behavior to me.

Done.
