We don't do this for the content shell APK with gyp - is there a reason your
doing this for content shell with GN or was it just testing?  I think it would
be best to keep gyp and GN the same - if so we can remove the changes to
ChromiumLinkerTestActivity.java / ContentShellActivity.java as well.

We definitely should be doing this for some target upstream so that we can
actually catch regressions before they are committed to chromium. I'll leave it
out of this change, but we should update gyp and gn at some point to use it.

Agreed, I'll take a look at enabling the linker tests and chrome_test_shell once
this CL lands.
