perf tools: Add variable display for VF make output

Adding dump of interesting build directories to the make VF=1 output.

  $ make VF=1
    BUILD:   Doing 'make -j4' parallel build

  Auto-detecting system features:

  ...                    sysconfdir: /home/jolsa/etc

Adding functions to print variable/text in features display -
feature_print_var/feature_print_text (feature_print_text is used in next
patches).
