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 libapi build mirroring the libbpf and libsubcmd build, so that it is installed in a directory along with its headers. A later change will modify the include behavior.
