Latencytop support needs too much debug-only features. As we don't build
debug images, this is wontfix for now.

| config LATENCYTOP
|         bool "Latency measuring infrastructure"
|         select FRAME_POINTER if !MIPS
|         select KALLSYMS
|         select KALLSYMS_ALL
|         select STACKTRACE
|         select SCHEDSTATS
|         select SCHED_DEBUG

You should check the complete config for differences.
