ktap doesn't build with recent kernels (e.g. 5.10.104-cip3 or 5.15.37)
and is not maintained anymore (latest release in 2013 and latest commit
more than 5 years ago):

-	  ktap is a script-based dynamic tracing tool for Linux
-
-	  It uses a scripting language and lets users trace the Linux

-	  insights with interoperability that allows users to tune,
-	  troubleshoot and extend kernel and application.
-	  It's similar to Linux Systemtap and Solaris Dtrace.
-
-	  ktap doesn't support kernels older than 3.1.
-
-	  To be able to resolve symbols in DSO and for sdt, you need to
-	  enable elfutils.
-
-	  Your kernel must have CONFIG_EVENT_TRACING,

-
-	  Buildroot automatically enables these in the kernel

I was going to say: is it not just a matter of adding EVENT_TRACING to
KTAP_LINUX_CONFIG_FIXUPS ?

But then...

This is now really removed from the kernel, so ktap would anyway need
patching.

So, applied to master, thanks.
