* config.shared: Emit everything which needs to be re-definable
via file descriptor 1; the generic stuff is emitted using redirection
onto fd 2.
* configure.in (package_makefile_rules_frag): New variable
which is used in the call to config.shared; redirect file descriptor 2
to ${package_makefile_rules_frag}.
