This is annoying. Without my last commit the build was failing with:

WARNING: [whatsnew/changelog:86] "::" found in "Lib/ctypes/test/test_functions.py::test_mro"
make[1]: *** [Makefile:51: build] Error 1
make[1]: Leaving directory '/home/runner/work/cpython/cpython/Doc'
Suspicious check complete; look for any errors in the above output or in build/suspicious/suspicious.csv.  If all issues are false positives, append that file to tools/susp-ignored.csv.
make: *** [Makefile:115: suspicious] Error 1

With the commit adding the ignore, it's failing with:

WARNING: Found 1/384 unused rules: whatsnew/changelog,,::,Lib/ctypes/test/test_functions.py::test_mro
make[1]: *** [Makefile:51: build] Error 1
make[1]: Leaving directory '/home/runner/work/cpython/cpython/Doc'
Suspicious check complete; look for any errors in the above output or in build/suspicious/suspicious.csv.  If all issues are false positives, append that file to tools/susp-ignored.csv.
make: *** [Makefile:115: suspicious] Error 1

Needless to say, the second error doesn't reproduce locally for me.
