Subject: [PATCH] perf ppc64le: Fix build failure when libelf is not present

References: bsc#1040940
Patch-mainline: v4.8-rc3
Git-commit: f046f3df665361d2f89e660f8c79ba164069f02a

arch__post_process_probe_trace_events() calls get_target_map() to
prepare symbol table. get_target_map() is defined inside
util/probe-event.c.

probe-event.c will only get included in perf binary if CONFIG_LIBELF is
set.  Hence arch__post_process_probe_trace_events() needs to be defined
inside #ifdef HAVE_LIBELF_SUPPORT to solve compilation error.
