[poky] [PATCH 1/1] scripts/multilib-check: Check for multilib build results

[Dongxiao Xu]

This script is used to check whether the multilib build for a certain
recipe outcomes the right files/directories.

The usage for the script is:

$ source oe-init-build-env
$ multilib-check recipeA recipeB ...

or

$ source oe-init-build-env
$ multilib-check world

This fixes [YOCTO #2038]
