ARM: move -march=* and -mtune= options to arch/arm/Makefile
My main motivations for this commit are: [1] Follow the arch/arm/Makefile style of Linux Kernel [2] Maintain compiler options systematically Currently, we give -march=* and -mtune=* options inconsistently: Only some of the CPUs pass -march=* and -mtune=* options. By collecting such options into the single place arch/arm/Makefile we can tell which options are missing at a glance. [3] Prepare for deprecating arch/*/cpu/*/config.mk Note: This commit just moves the compiler options so as not to change the behavior at all. It does not care about the correctness of the given options. Fox example, "-march=armv5te" might be better than "-march=armv4" for ARM946EJS, but it is beyond the scope this commit. Also, filling the missing -march=* and -tune=* is left to follow-up patches.
