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

However I don't know where you picked up a reference to commit
8738646c02 which is nonexistent in any of my repositories. The right
reference from RMK's devel-stable branch would be commit 5ffb04f669.
Please fix that and send to the patch system.
Nicolas
