- help
- GCC's -Wmaybe-uninitialized is not reliable by definition.
- Lots of false positive warnings are produced in some cases.

- If this option is enabled, -Wno-maybe-uninitialzed is passed
- to the compiler to suppress maybe-uninitialized warnings.

Choosing this option will pass "-O3" to your compiler to optimize
the kernel yet more for performance.

Choosing this option will pass "-Os" to your compiler resulting
in a smaller kernel.
