flake in generating build

I only got this once. I pulled and sync'd again and it didn't repro, so I tried going back to the rev above (362b714), but it didn't repro there either, so seems a bit flaky.

Any GN changes that might cause this recently? Vaguely reminiscent of  crbug.com/674213 .

I'm getting this too:

thakis@thakis:~/src/chrome/src$ time ninja -C out/gnand6 chrome_public_apk -j1000

In my case the explanation is that I just forgot to `gclient sync` after `git pull`, apparently.

Don't see any GN changes recently.

Maybe the recent changes to exe_and_shlibs_deps triggered this somehow?

Comment 5 by scottmg@chromium.org, May 26 2017 

Huh, I'm 98.67% positive I didn't forget to sync. But the scrollback is gone, so I can't prove anything unfortunately.

Status: Fixed (was: Untriaged)
Assuming this is fixed now.
