Thinking about it, we already have this. It's called "CONFIG_COMPILE_TEST".

It very much gets set by all{yes,mod}config, and it also says "we're
interested in testing the compile, not so much running the result".

So let's just make the DEBUG_INFO depend on !COMPILE_TEST.

Trivial oneliner patch (independent of the discussion about improving
the documentation), so I'll just apply it.

I can't imagine that this would be controversial:

config DEBUG_INFO
bool "Compile the kernel with debug info"
- depends on DEBUG_KERNEL
+ depends on DEBUG_KERNEL && !COMPILE_TEST
help

Hm?
