Dear Masahiro,

Generating boards.cfg gives me another trouble. I use Jenkins
(http://jenkins-ci.org/) for internal development. Even I can manually run
MAKEALL to generate boards.cfg, the same script under Jenkins cannot. I have
this error


./MAKEALL -c mpc83xx -c mpc85xx -c mpc86xx
Could not find boards.cfg

Looks like the script is trying to get the terminal window size. There is no
terminal for my case. Checking variable TERM, it is "dumb". I can make it work
by removing the two lines but I don't think that's the solution.

I am not an expert on python. Can you take a deep look? The host has ubuntu
12.04.3 with python 2.7.3.
