[PATCH] Check ARCH and IS_64_BIT instead of IS_X86_64 in perf

[H.J. Lu]

IS_X86_64 is never defined nor necessary.  We check check ARCH and
IS_64_BIT instead.

ifeq ($(IS_X86_64),1)

can be replaced by

ifeq ($(ARCH)$(IS_64_BIT), x861)

If IS_64_BIT is 1, we can replace

ifneq (${IS_X86_64}, 1)

with

ifneq ($(ARCH), x86)
