Merge tag 'ktest-fix-make-min-failed-build-for-real' of git://git.kernel.org/pub...

While demoing ktest at ELC in 2012, it was embarrassing that the
make_min_config test failed to work because the snowball board I was
testing it against had a config that would not build.  But the
make_min_config only tested the testing part and ignored build failures.
The end result was a config file that would not boot.

This time, for real.
