Factor out x86-isms and add cross compile support
This patch cleans up and refactors the Makefiles to better allow new architectures to be added: - remove unused Makefile definitions - import Makefile definitions from top level rather than redefining - move x86 specific CFLAGS to inside ifeq() blocks - remove x86 inline asm - allow $(FORMAT) to be overridden: this is necessary as there exists no EFI or PE/COFF aware objcopy for ARM Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org>
