Are you sure it appears after building? I thought the syncing of that was done in //DEPS (or similar), so this would happen after a sync, but I could be missing something.

In any case, that file isn't used any longer; I'll send out a CL to remove it later today.

Out of curiosity, is this profile causing an issue? We sync other profiles to that directory, and they're very much needed, so if it is, we should probably work on fixing that, too. :)

You are right. The file appeared just after I run `gclient sync`
My .gclient is like below.
```
solutions = [
    {
        "url": "https://chromium.googlesource.com/chromium/src.git",
        "managed": False,
        "name": "src",
        "deps_file": ".DEPS.git",
        "custom_deps": {},
    },
]
target_os = [ 'android' ]
```

It just requires me to run `git clean -df`.

Remove the old AFDO profiles for Android.

We have an old profile hanging out in Android checkouts from before the
days of autorolling them directly into Chromium. It's not breaking
anything, but since it shows up in git status and is otherwise unused...

Bug:  864893 
Test: rm chrome-profile-3309-text.prof && gclient sync. Profile's gone.

You may need to remove the old profile once more, but ^ should keep it from coming back.

We already have the new profile bits in Chromium's .gitignore, so that shouldn't show up as an untracked file.

If I missed something, please let me know, and thanks for flagging this!

Thanks!
