xattr missing for MacOSX

[Alan Snelgrove]

The latest rsync change disables xattr when there is no lgetxattr()  
function.
There is however, an option of the getxattr function to act on the  
symlink.

      XATTR_NOFOLLOW  do not follow symbolic links.  getxattr() normally
                      returns information from the target of path if  
it is a
                      symbolic link.  With this option, getxattr()  
will return
                      extended attribute data from the symbolic link  
instead.

Is it possible to have xattr support back for Mac OSX.
