All these failures and errors are due to trying to create
a hardlink to a symlink and getting an "Operation not supported" error.

Can you send the output of this command?
  $ grep -E "(LINK_F|LINKAT)" lib/config.h

What file system type are you running this one?

I suspect that this might help?

diff --git a/lib/linkat.c b/lib/linkat.c
