Subject[PATCH 71/79] libperf: Add install targets
Date
Add install targets (mostly copied from lib/bpf),
it's now possible to install libperf with:

$ make DESTDIR=/tmp/krava install
INSTALL libperf.a
INSTALL libperf.so
INSTALL libperf.so.0
INSTALL libperf.so.0.0.1
INSTALL headers
INSTALL libperf.pc

$ find /tmp/krava/
/tmp/krava/
/tmp/krava/include
/tmp/krava/include/perf
/tmp/krava/include/perf/evsel.h
/tmp/krava/include/perf/evlist.h
/tmp/krava/include/perf/threadmap.h
/tmp/krava/include/perf/cpumap.h
/tmp/krava/include/perf/core.h
/tmp/krava/lib64
/tmp/krava/lib64/pkgconfig
/tmp/krava/lib64/pkgconfig/libperf.pc
/tmp/krava/lib64/libperf.so.0.0.1
/tmp/krava/lib64/libperf.so.0
/tmp/krava/lib64/libperf.so
/tmp/krava/lib64/libperf.a
