Use $(CROSS_COMPILE)size to determine the bss size
from vmlinux.
The problem is introduced in:
commit 5ffb04f6690d71fab241b3562ebf52b893ac4ff1
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
