x86/kconfig: Select ARCH_WANT_FRAME_POINTERS again when UNWINDER_FRAME_POINTER=y
[ Upstream commit 66ee3636 ] It took me some time to understand the purpose of the tricky code at the end of arch/x86/Kconfig.debug. Without it, the following would be shown: WARNING: unmet direct dependencies detected for FRAME_POINTER because 81d38719 ("x86/kconfig: Consolidate unwinders into multiple choice selection") removed 'select ARCH_WANT_FRAME_POINTERS'. The correct and more straightforward approach should have been to move it where 'select FRAME_POINTER' is located. Several architectures properly handle the conditional selection of ARCH_WANT_FRAME_POINTERS. For example, 'config UNWINDER_FRAME_POINTER' in arch/arm/Kconfig.debug.
