Subject: lib: fix kconfig dependency on ARCH_WANT_FRAME_POINTERS
When LATENCYTOP, LOCKDEP, or FAULT_INJECTION_STACKTRACE_FILTER is enabled
and ARCH_WANT_FRAME_POINTERS is disabled, Kbuild gives a warning such as:
WARNING: unmet direct dependencies detected for FRAME_POINTER
Depends on [n]: DEBUG_KERNEL [=y] && (M68K || UML || SUPERH) || ARCH_WANT_FRAME_POINTERS [=n] || MCOUNT [=n]
Selected by [y]:
- LATENCYTOP [=y] && DEBUG_KERNEL [=y] && STACKTRACE_SUPPORT [=y] && PROC_FS [=y] && !MIPS && !PPC && !S390 && !MICROBLAZE && !ARM && !ARC && !X86
Depending on ARCH_WANT_FRAME_POINTERS causes a recursive dependency error.
ARCH_WANT_FRAME_POINTERS is to be selected by the architecture, and is
not supposed to be overridden by other config options.
