well there is another thing must be changed .. the kernel Makefile is
written for gcc and the compilation options are written for gcc .. so i
have another step to look for it is the mapping between gcc flags and my
compiler flags .. the build process depends on a hirarichy Makefiles ..
it's hard to check all makefiles in all the hirarichy checking for gcc
options used to compile the kernel .. are they documented anywhere or is
there any way to them (before-when-after) kernel compilation
I don't know about any documentation unfotunately. But all the compiler
options and stuff is located in the top-level Makefile, Rules.make and
one Makefile for each platform. All the others just use ready-made
compilation commands.
That's not true, every single Makefile in the kernel can add compiler
flags for the compilation in this subdirectory.
Examples are e.g. drivers/input/joystick/iforce/Makefile adding
-Werror-implicit-function-declaration or drivers/acpi/Makefile
adding -Os.

I think it's better to create a small shell script that scans all
Makefiles and extract the compiler options from everyfile and then
remove the repeated flags .. it's something like a piping "find | grep |
awk | sort -u" will solve it
