[Buildroot] [PATCHv3 0/5] Graph about installed size per package

Hello,

Here is the third iteration of the patches adding a 'size-stats'
feature, which mainly allows to generate a pie chart of the size
contribution of each package to the overall root filesystem size.

Changes since v2:

 - Use print0 in find and -0 in xargs to support spaces in filenames,
   just in case. Suggested by Jérôme Pouiller.

 - Support custom skeleton locations, instead of assuming the skeleton
   comes from system/skeleton.

 - Fix the size-stats target to actually call the size-stats script,
   and not graph-size, which was the old name of the script in
   previous versions of the series.

 - Fix usage of the size-stats target in out of tree build
   situations. For consistency reasons, we chose to mimic what
   graph-depends already does, even if size-stats does not necessarily
   need to be executed from within CONFIG_DIR.

 - Add one patch to make sure that 'make clean' removes the graphs/
   subdirectory in the output directory, which wasn't done today. This
   issue isn't specific to size-stats, and already existed with
   graph-build and graph-depends.

Comments:

 - Jérôme Puiller suggested to add a warning for removed
   files. However, many files are removed in the target-finalize step
   (man pages, etc.) and we don't want to have gazillions of warnings
   about these completely normal file removals.

Thomas Petazzoni (5):
  Makefile: remove the graphs/ dir on 'make clean'
  pkg-generic: add step_pkg_size global instrumentation hook
  support/scripts: add size-stats script
  Makefile: implement a size-stats target
  Dummy testing packages
