Patch for Freescale toolchain

[Amit Kucheria]

Hi Chih,

Just try this change to arch/arm/Makefile. Sorry, it isn't a real
patch, just a cut/paste job.

-arch-$(CONFIG_CPU_32v7)                :=-D__LINUX_ARM_ARCH__=7
$(call cc-option,-march=armv7-a,-march=armv5t
-Wa$(comma)-march=armv7-a)
+arch-$(CONFIG_CPU_32v7)                :=-D__LINUX_ARM_ARCH__=7
$(call cc-option,-march=armv7a,-march=armv5t -Wa$(comma)-march=armv7a)
