This means that rather than having to edit three places (asm/unistd.h for the total number of system calls, uapi/asm/unistd.h for the system call numbers, and arch/arm/kernel/calls.S for the call table) we have only one place to edit, making the process much more simple. The scripts have knowledge of the table padding requirements, so there's no need to worry about __NR_syscalls not fitting within the immediate constant field of ALU instructions anymore.

The flags we set are intended for converting a few ELF files into raw binaries, and thus the flags chosen are problematic for some other uses which do not expect a raw binary result, e.g. the upcoming lkdtm rodata test: http://www.openwall.com/lists/kernel-hardening/2016/06/08/2 This patch localises the objcopy flags such that they are only used for the cases we require them for today.

In case of ARM_SINGLE_ARMV7M, we end up also exporting them, but that appears to be a mistake, and we should treat it the same way as ARCH_MULTIPLATFORM here. 'make W=1' warns about this because it passes -Wmissing-includes to gcc and the directories are not actually present.

It looks clumsy, so let's display the same message only once. This commit moves the log rules from arch/arm/boot/Makefile to arch/arm/Makefile. I did not delete them completely because *Image are the final targets that users are interested in.
