- Write kernel log output directly via the hypervisor console.
- This is useful for kernel debugging when your machine crashes very
- early before the console code is initialized. For normal operation
- it is not recommended because it looks ugly and doesn't cooperate
- with klogd/syslogd. You should normally N here,
- unless you want to debug such a crash.

- depends on DEBUG_INFO
- default ""
- help
- Debug info can be large, and flags like
- `-femit-struct-debug-baseonly' can reduce the kernel file
- size and build time noticeably. Such flags are often
- helpful if the main use of debug info is line number info.
