[RFC PATCH] x86/Kconfig: Disable KASLR on debug builds

[Borislav Petkov]

From: "Borislav Petkov (AMD)" <bp@xxxxxxxxx>

Having KASLR enabled makes debugging a kernel completely useless because
virtual addresses are not stable, leading to people poking at kernel
internals to have to go and rebuild with RANDOMIZE_BASE=off.

Just disable it on debugging builds where it is not needed anyway.
