x86/kconfig: Select ARCH_WANT_FRAME_POINTERS again when UNWINDER_FRAME_POINTER=y
[ Upstream commit 66ee3636eddcc82ab82b539d08b85fb5ac1dff9b ]
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
81d387190039 ("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.
