When restarting builds on Hydra, the log for the first build attempt is
lost.  However, I'm in the habit of making private copies of these logs
before restarting jobs, so I have a copy of both.

The nss-3.29.3 build on armhf also failed:

  https://hydra.gnu.org/build/1906025

This is not really sustainable.  A single build attempt takes 7 hours on
armhf, and about 40 hours on mips.  When the failure occurs, it causes
hundreds of other dependency failures, which must be restarted manually,
one at a time, via the web interface.  (We have a way to restart *all*
dependency failures, but that results in a huge amount of wasted work
for Hydra).

We need test suites to be robust on heavily loaded build machines.

Is there a compelling reason not to revert this update for now?
