Subject: [PATCH v1 06/14] perf build: Install libtraceevent locally when building
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.
