commit: http://git.buildroot.net/buildroot/commit/?id=aaef2cad852377f8ed9ac5cc3282c9741f81c7d4
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Certain tracing related options are required to be able to build ktapvm.ko, enable those.
Enable CONFIG_FUNTCTION_TRACER as otherwise, CONFIG_EVENT_TRACING won't stick. (Some
tracer needs to be enabled for this).
[Peter: add a note to ktap Config.in explaining this is done]

Your kernel must have CONFIG_EVENT_TRACING,
CONFIG_PERF_EVENTS, and CONFIG_DEBUG_FS enabled to compile.
+ Buildroot automatically enables these in the kernel configuration.
