Also, does utimensat(AT_FDCWD,"file",NULL,0) work, and it is just the
AT_SYMLINK_NOFOLLOW variant that fails with ENOSYS?  If so, I see at least
one problem in lib/utimens.c - it shares a static variable between
lutimens and fdutimens, which means that if lutimens detects
AT_SYMLINK_NOFOLLOW failure, then fdutimens fails to even try utimensat in
the future.

Both failures depend on 'touch -h', which is new to coreutils 8.1; there
is no regression, because prior to coreutils 8.1, you couldn't request the
use of AT_SYMLINK_NOFOLLOW in the first place.
