[Bug-tar] incorrect reporting of harlink mismatch

[Cezary Sliwa]

Dear tar,

To reproduce the bug, enter these shell commands

==================

test -e a && echo "\"a\" already exists"
test -e a && exit

set -e -x

echo "creating test data..."
mkdir a
touch a/x
ln -s x a/y
ln a/y a/z

echo "creating test archive..."
tar cf a.tar a

echo "comaparing: "
tar vdf a.tar

echo "replacing a hardlink: "
rm a/z
ln -s x a/z

echo "comaparing: "
tar vdf a.tar

==================

I get

a/y: Not linked to a/y

which is evidently incorrect.
