Commit Message

Add defconfig for UML and a fragment that can be used to configure other
architectures for building KUnit tests. Add option to kunit_tool to use
a defconfig to create the kunitconfig.

Are these above config options necessary? I don't think they're part of
the patch series anymore so it looks odd to enable the OF unittests and
i2c configs.

Oh whoops, I forgot that we dropped the OF_UNITTEST from this
patchset. Will fix.
