adapt to kernel-3.4.9

with this commit, kconfigtest can be run under kernel-3.4.9
I tried the latest version kernel-3.7rc2, but there's more kconfig script bugs which i don't know how to hack.

maybe the tokenization process of kconfiglib is too strict?
i like strict, but using more and more hacks to adapt to kconfig bugs is not a long-term solution.
mconf.c is using yacc, isn't it? are we able to use the same algorithm of yacc? i really know nothing about yacc except this famous name.

Is there some way we can run the testsuit without patching?
I have read kconfigtest.py, but i'm new to python and kernel makefile so I don't quite understand it yet, can you give me some infomation?
