The perf build currently has a '-Itools/lib' on the CC command line. This causes issues as the libapi, libsubcmd, libtraceevent, libbpf headers are all found via this path, making it impossible to override include behavior. Change the libtraceevent build mirroring the libbpf, libsubcmd, libapi and libperf build, so that it is installed in a directory along with its headers. A later change will modify the include behavior. Similarly, the plugins are now installed into libtraceevent_plugins except they have no header files.
