Subject: [PATCH 0/3] tools/tracing: Use tools/build makefiles like perf

tools/tracing and tools/verification/rv are using standalone Makefiles.
However, This approach has some drawbacks. For example, code
duplication and lack of proper dependency handling, making things
harder for users. 

Linus suggested using perf's build system, and it is indeed the best way to go.

This series replaces tools/tracing and tools/verification/rv makefiles
with makefiles inspired by perf and objtool that use tools/build/
infrastructure.

Thanks, Arnaldo, for the pointers via chat.
