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.
