ARM: 8588/1: localise objcopy flags
We currently define OBJCOPYFLAGS in the top-level arm Makefile, and thus
these flags will be passed to all uses of objcopy, kernel-wide, for
which they are not explicitly overridden. 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.
