I have used debug info on allyesconfig in the past to run statistics
on the resulting binary. It's still useful, even though quite slow.
Make it depend on !EXPERT or somesuch? I agree for normal usages it's fine.

BTW you probably also want to do the same for the x86 instruction
decoder test. It seems to be the biggest compile time waster in
allyesconfig and I usually disable it too.
