First failing build https://uberchromegw.corp.google.com/i/internal.client.clank/builders/monochrome-feedless-builder/builds/3168

If I revert https://chrome-internal.googlesource.com/clank/internal/apps/+/e28e4df196105ab7de966e9fe88a718c1cf4d6d2 the step succeeds.

To repro, modify components/feed/features.gni to set enable_feed_in_chrome = false;

gn args of

target_os = "android"
target_cpu= "arm"
use_goma = true
is_debug = false
is_official_build = true
use_signing_keys = true
is_chrome_branded = true

And then run "gn gen <out_dir>"

skym@skym-linux2:/usr/local/google/code/clankium/src$ gn gen out/Release/
