The coreutils test mkdir/p-3.sh currently fails on macOS, AFAICT as a
result of the gnulib change:
e4399abd41 (savewd: port to native MS-Windows, 2024-08-27)
The relevant part of the test is:
mkdir no-access || framework_failure_
p=$(pwd)
(cd no-access && chmod 0 . && mkdir -p "$p/a/b" u/v) 2> /dev/null
test $? -eq 1 || fail=1
Essentially, if cwd lacks search permission, relative paths in the list
passed to savewd_process_files end up resolved relative to the dir used
to process any previous absolute path in the list.
