tools lib traceevent: Export dynamic symbols used by traceevent plugins Traceevent plugins need dynamic symbols exported from libtraceevent.a, otherwise a dlopen error will occur during plugins loading. This patch uses dynamic-list-file to export dynamic symbols which will be used in plugins to perf executable. The problem is covered up if feature-libpython is enabled, because PYTHON_EMBED_LDOPTS contains '-Xlinker --export-dynamic' which adds all symbols to the dynamic symbol table. So we should reproduce the problem by setting NO_LIBPYTHON=1.
