This suggests that running make check as root is not a routine part of
coreutils pre-release work, and that nobody has run a make check as root
since Jan 30! That's quite surprising given that running a make check as
root has long been encouraged. The README even says

(This is not the first time I've hit test failures when checking
released coreutils as root, though it isn't *common*.)

Looks good to me, and fixes the bug. make check now passes as root.
