There is an unexplained error when the chromium linker is turned on for
the content shell.  It manifests (in logcat) as:

This does not occur with the chrome shell.  The change in

  https://codereview.chromium.org/371943003/

corrects chromium linker operation and resolves crbug/388356, but to land that
requires that we turn off the chromium linker on the content shell first.
