Subject[PATCH] X86: Makefile: Replace -pg with CC_FLAGS_FTRACE
Date
In preparation for x86 supporting ftrace built on other compiler
options, let's have the x86 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.
