Description of problem:

Remote archiving with --file HOSTNAME:F option doesn't work.
The function needs the path for rsh command.
The configure script for tar detects the path.
However, the spec file of tar doesn't require rsh package
in BuildRequire field.

Version-Release number of selected component (if applicable):
1.20-5.fc11 raw hide. But tar shipped with EL4 has the same problem.

How reproducible:

 $ tar -c -f localhost:/tmp/x.tar /boot
 tar: localhost\:/tmp/x.tar: Cannot open: Input/output error
 tar: Error is not recoverable: exiting now

Steps to Reproduce:
1. Just invoke tar with --file HOSTNAME:F argument
2.
3.
  
Actual results:
Reporting an error.

Expected results:
The archive is created at the remote host.
