This may be so, but the installed dh_strip-nondeterminism fails in the
same way:

,----
| $ dh_strip_nondeterminism --help
| dh_strip_nondeterminism: "debian/control" not found. Are you sure you are in the correct directory?
`----

The same error is seen with "dh --help" (which worked in 12.4, although
it is not documented) and "dh --list", which is supposed to work from
any directory.
