[U-Boot] [PATCH] ARM: refactor compiler options in config.mk
Every ARM cpu config.mk (arch/arm/cpu/{CPUDIR}/config.mk) defines:
PLATFORM_RELFLAGS += -fno-common -ffixed-r8 -msoft-float
So, this patch moves the common compiler options to arch/arm/config.mk.

Note: This commit keeps arch/arm/cpu/s3c44b0/config.mk untouched. because arch/arm/cpu/s3c44b0/* is the remainder of dead board and is expected to deleted soon. See 'ARM: s3c44b0: remove remainders of dead board' patch posted by me, Aug 19, 2013.

Applied to u-boot-arm/master as a prerequisite to the "ARM: use r9 for gd instead of r8" series, thanks!
