2.4.9 arch/i386/Makefile already does this

ifdef CONFIG_MK6
CFLAGS += $(shell if $(CC) -march=k6 -S -o /dev/null -xc /dev/null >/dev/null 
2>&1; then echo "-march=k6"; else echo "-march=i586"; fi)
endif

ifdef CONFIG_MK7
CFLAGS += $(shell if $(CC) -march=athlon -S -o /dev/null -xc /dev/null 
>/dev/null 2>&1; then echo "-march=athlon"; else echo "-march=i686 -mal
ign-functions=4"; fi)
endif
