Steven Rostedt 656ee82cc8 kbuild: create new CFLAGS_REMOVE_(basename).o option 
We currently have a way to add special CFLAGS to code, but we do not have a
way to remove them if needed.

With the case of ftrace, some files should simply not be profiled. Adding
the -pg flag to these files is simply a waste, and adding "notrace" to each
and every function is ugly.

Currently we put in "Makefile turd" [1] to stop the compiler from adding -pg
to certain files. This was clumsy and awkward.

This patch now adds the revese of CFLAGS_(basename).o with
CFLAGS_REMOVE_(basename).o.  This allows developers to prevent certain
CFLAGS from being used to compile files. For example, we can now do

CFLAGS_REMOVE_string.o = -pg

to remove the -pg option from the string.o file in the lib directory.

Note: a space delimited list of options may be added to the REMOVE macro.

[1] - what David Miller called the workaronud to remove -pg
