The same thing is needed in test-ptsname_r.c:

ptsname_r-tests: Avoid unused function warning.

The patch is OK.
However, I would appreciate if you don't call a warning a "build failure"
or an "error".
Reasons:
1. Adding -Wer
* tests/test-canonicalize.c: Protect the inclusion of null-ptr.h
with the same guard as that used to protect usage of the null_ptr
function, so that one doesn't get a -Werror=unused build failure,
warning about the function being defined but unused.
* tests/test-canonicalize-lgpl.c: Likewise.
