In 2.6 arch/i386/Makefile looks like this;

cflags-$(CONFIG_M686)           += -march=i686
cflags-$(CONFIG_MPENTIUMII)     += $(call check_gcc,-march=pentium2,-march=i686)
cflags-$(CONFIG_MPENTIUMIII)    += $(call check_gcc,-march=pentium3,-march=i686)
cflags-$(CONFIG_MPENTIUM4)      += $(call check_gcc,-march=pentium4,-march=i686)

et al for the other cpu CONFIG options.

IOW it pretty much makes the right choices w/o editing.
