Thus this change also brings in NaCl changes from
11084:11126 inclusive.

This is the same change as https://codereview.chromium.org/13129002/ but with
the download_toolchain fix to make sure the arm toolchain
is downloaded when target_arch=arm.

This time I've been sure to a green cros_daisy tryjob.

You can just TBR me when you're landing a change that I already LGTMed. Or you
can reuse the same changelist if you prefer.

I'll let somebody else look at the script...  pepper stuff still lgtm

Step "update" is always a major failure.
Look at the try server FAQ for more details.
