Urvang, I'd like to land this pre-release so we can be sure of some of the
exotic toolchains before finalizing 0.4.2 -- I already had to restore a mips
workaround.
You can wait for the bots and when I'm back around before we try to submit.

lgtm

Looks fine; we can wait for the bots to be stable before starting CQ.

P.S. One bot seems to be failing now, but it seems unrelated.

I saw that, gn for a deleted directory. Not sure if a rebase would solve it, I
can do one prior to submit, this checkout is only a little over a day old.
