Sort alphabetically (please fix GYP version too)

Done.

This is not needed for GN.

Done.

Please add "//build/config/sanitizers:deps" as well, it's likely (but not
necessarily) needed in order to build with sanitizers enabled.

[kjellander_webrtc, 2016/08/23 10:03:32]

Is rtc_base really needed? rtc_base_approved is usually enough.

Can you add that dependency to the GYP target too?

[ivoc, 2016/08/23 11:38:50]

Done.

[ivoc, 2016/08/23 11:38:50]

According to gn check it has to be rtc_base, because webrtc/base/format_macros.h
is included. I think that should be fine since this is a standalone test
executable.

Will add it to GYP as well.
