ptxdist: rework 'print' command
- 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>ยท...
to dump a useful list of many variables that may or may not be defined.
