Look in the kernel source, specificially arch/arm/Makefile - depending
on the version you'll see KBUILD_CFLAGS define dusing $(arch-y) and
$(tune-y) which are set based on CONFIG_CPU_XXX being set.

You might want to also build your kernel, then look for the line "+ make
ARCH=arm 'HOSTCC=ccache /usr/bin/gcc -B/usr/bin//' uImage" that builds
uImage.  Open up another shell, then execute "./ltib -m shell" and cd
into your kernel build directory (rpm/build/kernel-xxx usually), and
execute the make target that build uImage.  However add "V=1" after the
make; this causes the build to show you the compiler command line so you
can see the -mcpu= and -march= selections your kernel is making. 
Remember to exit this new shell, or "ltib" will fail to build (due to
.lock_file existing).

Hope this helps.
