These were originally deleted as "not important" but, actually we need them
in place if we want to be able to use autoconf on software that provides
atf-based tests. (That includes being able to rebuild autotest from scratch
on the Kyua cluster machines, as the automated setup does.)
These were originally deleted by mistake (because they were not yet being
installed) and are actually necessary.
This should have been part of r260576 but I missed committing this
directory.
