Subject: ptxdist: rework 'print' command
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

 - avoid "recipe for target '...' failed" messages
 - generate '<variable>=<value>' when running in verbose mode
 - produce and empty value instead of an error when "-k" is used

This makes is possible to use
$ ptxdist -v--k make print-<VAR1> print-<VAR2>·...
to dump a useful list of many variables that may or may not be defined.
