Run list-packageconfig-flags.py on wrlinux's platform in which
the oe-core layer and bitbake layer in different directories:
----
../layers/oe-core/scripts/contrib/list-packageconfig-flags.py
Traceback (most recent call last):
File "../layers/oe-core/scripts/contrib/list-packageconfig-flags.py", line 28, in <module>
import bb.cache
ImportError: No module named bb.cache
----
The script import bb module from bitbake lib dir, the previous
lib dir was hardcode and only worked on poky but not for others.
In this situation, look for bitbake/bin dir in PATH could fix this issue.
