Is this target not needed anymore?

[mbonadei, 2017/08/29 06:45:29]

I think it is used as an "umbrella target" to link all the tests in the deps
list into a single executable.

But (not related to this CL) I see that there is also webrtc_tests and it
contains some unit tests, so maybe we can merge them together or keep unit tests
separated from webrtc_tests.

I will follow up on this.

I'll keep it for now then.
