Fixed:
* The os.link() reqiures write permission on the src file (suppose the
src file belongs to another user, then you need write permission to harlink to
it since the link count would change)
* Print more info when failed to copy
The warning was like:
WARNING: Could not copy license file COPYING: [Errno 1] Operation not permitted
We couldn't know which recipe print the warning from this message.
