No, it's a waste of disk space.
Why would you knowingly compile something you know you can't use?
That's the whole point of COMPILE_TEST.
Note that when you want real coverage and you use `allyesconfig`
and/or `allmodconfig` then CONFIG_OF is also enabled on platforms
which support it.

This is better.
