I'd rather not go there. In practice it doesn't make much of a difference -
it just ensures that COMPILE_TEST can run on architectures which don't
support I2C. I think 0day only finds it because they select COMPILE_TEST
and then selectively disable I2C (and maybe other configuration options)
to catch problems like this.
