[PATCH 1/3] x86, boot: Use the usual -y -n mechanism for objects in vmlinux

From: Josh Triplett
Date: Mon Mar 10 2014 - 16:32:17 EST


Switch VMLINUX_OBJS to vmlinux-objs-y, to eliminate Makefile
conditionals in favor of vmlinux-objs-$(CONFIG_*) constructs.

This does not change the generated code at all.
