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.
