Subject: [PATCH] x86: tinyconfig: fix warning for 'make ARCH=x86_64 tinyconfig'

Kconfig emits a warning for the following command:

$ make ARCH=x86_64 tinyconfig
[ snip ]
.config:1380:warning: override: UNWINDER_GUESS changes choice state

When X86_64=y, the unwinder is exclusively selected from the following
three options:

- UNWINDER_ORC
- UNWINDER_FRAME_POINTER
- UNWINDER_GUESS

However, arch/x86/configs/tiny.config only specifies the values of the
last two. UNWINDER_ORC must be explicitly disabled.
