>Description:

Running the ATF tests on real hardware, more than 100 file system
tests are now failing.  For logs, see

  http://www.gson.org/netbsd/bugs/build/amd64-baremetal/commits-2020.04.html#2020.04.05.00.36.25

The problem started during the period of build breakage that ended
with

  2020.04.05.00.36.25 christos src/etc/Makefile 1.443

It's hard to tell exactly when the build breakage started as the build
has been failing in several different ways and may or may not have
built inbetween them, but at least 2020.04.04.19.26.51 still built
on i386.

There has been no automated report to current-users as the i386
testbed responsible for sending those is currently unable to run the
tests to completion because of the issue discussed in PR 54786.

>How-To-Repeat:

Run the ATF tests on amd64.
