If libtraceevent isn't installed or NO_LIBTRACEEVENT=1 is passed to the build, don't compile in libtraceevent and libtracefs support. This also disables CONFIG_TRACE that controls "perf trace". CONFIG_TRACEEVENT is used to control enablement in Build/Makefiles, HAVE_LIBTRACEEVENT is used in C code. Without HAVE_LIBTRACEEVENT tracepoints are disabled and as such the commands kmem, kwork, lock, sched and timechart are removed. The majority of commands continue to work including "perf test".

For example, the perf extension was previously perf.so but now maybe perf.cpython-310-x86_64-linux-gnu.so. Compute the extension using Python and then use this in the target name. Doing this avoids the "perf.so" target always being rebuilt.
