This may have been a question better for the coreutils@gnu.org list,
rather than opening up a new bug report.  As such, I tagged this as not
a bug, and marked it closed; but we can reopen it if you can propose
better wording that would avoid further confusion.

It made sense to me, short for:

"We are skipping this test, since you are not running the test on
GNU/Hurd, which is the only platform known to be affected by the problem
exposed by the test"

That doesn't read right to me, since you _aren't_ running on GNU/Hurd,
but GNU/Linux.

No.  The test can only pass on a system where getuid() can fail, and the
only known platform where that is the case is GNU/Hurd (GNU/Linux does
not provide the extension of a getuid() that can fail by executing a
process outside the realm of POSIX process ids).
