bug#42633: 8.32 make check as root failure of rmdir/ignore.sh

[Nick Alcock]

I get an ERROR when running rmdir/ignore.sh as root (but not when
running as non-root). The running system has coreutils 8.31 installed;
The source tree, /usr/src/coreutils/x86_64-loom, is a loopback mount of
an xfs filesystem dedicated only to this build. (The build subdir
shai-build has nothing special about it.)

The failure observed is described in a comment in the test as applying
only to 8.31 and below: I don't *think* it can be mistakenly running the
host touch(1), can it?

(This is all built from a bootstrapped git checkout with a
locally-updated gnulib, updated five minutes before I did the build.)
