[PATCH] ARM: zImage: Use $(CROSS_COMPILE)size to get .bss size

[Thomas Weber]

Use $(CROSS_COMPILE)size to determine the bss size
from vmlinux.

The problem is introduced in:
commit 8738646c02064d38f6fb056eb039ebf9138c5434

ARM: zImage: make sure appended DTB doesn't get
overwritten by kernel .bss

This fixes following error message:

size: arch/arm/boot/compressed/../../../../vmlinux:
File format is ambiguous

size: Matching formats:
elf32-littlearm
elf32-littlearm-symbian
elf32-littlearm-vxworks
