[OE-core] [PATCH] scripts: Add ksize.py and dirsize.py
Darren Hart

Mon Oct 28 14:32:40 UTC 2013
Fixes [YOCTO #5388]
These scripts can be useful when working to reduce the size of the Linux
kernel and the root filesystem.
ksize.py displays the kernel build size by the built-in.o files.
dirsize.py displays the various sizes of the components of the root
directory.
