[U-Boot] Python subprocess module missing in multiconfig.py

[david at plentovichdesign.com]

Hello.  I read the posts a couple days ago about the Python issues with
Kconfig feature.  I didn't see a resolution on how this would be fixed.  I
am running Ubuntu 14.04LTS, building u-boot and the problem I have is that
the eldk tools have a older python (2.7.3) which does not have the
subprocess module but the current Ubuntu python (2.7.6) does include the
subprocess module.  When I add the eldk (cross compiler) path before my
env $PATH the defconfig fails in multiconfig.py (uses the python in the
eldk toolkit).  Can I just remove python from the eldk tools (so the newer
python will be used) or is that older python version required for some
other script in the cross compiler?
