[PATCH v8 3/5] arm64: replace -pg with CC_FLAGS_FTRACE in mm/kasan Makefile

[Torsten Duwe]

  In preparation for arm64 supporting ftrace built on other compiler
  options, let's have makefiles remove the $(CC_FLAGS_FTRACE)
  flags, whatever these may be, rather than assuming '-pg'.

  There should be no functional change as a result of this patch.
