perf, MIPS: Support cross compiling of tools/perf for MIPS
Changes: v4: Fix the cosmetic issue of redundant dot-ops v3: Change rmb() to use SYNC v2: Include mips unistd.h and define rmb()/cpu_relax() in tools/perf/perf.h Signed-off-by: Deng-Cheng Zhu <dengcheng.zhu@gmail.com> Acked-by: Ralf Baechle <ralf@linux-mips.org> Cc: David Daney <ddaney@caviumnetworks.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Paul Mackerras <paulus@samba.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
