linux.mk: enable options for ktap
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] Signed-off-by: Anders Darander <anders@chargestorm.se> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

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.
