Hi Yoyo,

Could you please take a look at this?

Thanks,
Vaclav

LGTM

By the way, the TEST= line is for instructions to the QA team, so you can omit
it in CLs like this which do not call for manual testing.

Thanks Yoyo,

I tend to put the TEST=N/A there in case the QA people wonder whether the test
is missing on purpose or not.

Adding ben@ to TBR for the straightforward *.gypi changes.
