perf tools: Enable libtraceevent dynamic linking
Currently we support only static linking with kernel's libtraceevent (tools/lib/traceevent). This patch adds libtraceevent package detection and support to link perf with it dynamically. The libtraceevent package status is displayed with: $ make VF=1 LIBTRACEEVENT_DYNAMIC=1 ... ... libtraceevent: [ on ] Default behavior remains the same (static linking). Committer testing: $ make LIBTRACEEVENT_DYNAMIC=1 VF=1 O=/tmp/build/perf -C tools/perf install-bin |& grep traceevent Makefile.config:1090: *** Error: No libtraceevent devel library found, please install libtraceevent-devel. Stop. $ Signed-off-by: Michael Petlan <mpetlan@redhat.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> LPU-Reference: 20210428092023.4009-1-mpetlan@redhat.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
