graph-size -> size-stats ?

But with that fixed I get:
$ make O=test/xfsprogs/ size-stats
Traceback (most recent call last):
  File "/home/naourr/git/buildroot/support/scripts/size-stats", line 217, in <module>
    pkgdict = build_package_dict(args.builddir)
  File "/home/naourr/git/buildroot/support/scripts/size-stats", line 68, in build_package_dict
    with open(os.path.join(builddir, "build", "packages-file-list.txt")) as filelistf:
IOError: [Errno 2] No such file or directory: 'test/xfsprogs/build/packages-file-list.txt'

But this file exist:
$ ls test/xfsprogs/build/packages-file-list.txt
test/xfsprogs/build/packages-file-list.txt

Also I noticed that the man pages (and headers) 
are taken into account in packages-file-list.txt:
[...]
tmux,./usr/bin/tmux
tmux,./usr/share/man/man1/tmux.1

Since they are removed at the end, I think we want to 
remove them from packages-file-list.txt during
TARGET_DIR cleanup ?

Best regards,
Romain
