Kconfig test scripts

[Sam Ravnborg <sam@ravnborg.org>]

Hi all.

Often when I hack on Kconfig I have missed a set of test cases,
that would allow me to verify that I did not introduce any regressions.

I have not anything fancy in my mind and I spent
a little time on the attached today.
The following is obviously missing a lot a features - but this
would allow me to get started adding simple test cases.

The idea is that each test cases consist of a full
Kconfig file and the resulting output.

Anyone have something better than this,
or maybe some brilliant ideas how to do this much better?

	Sam
