Are you sure that CONFIG_DTB_FILE was exported correctly?
Something as simple as that, could be the cause of the issue.

In my build script I have:

CONFIG_DTB_FILE=/path/to/vexpress-v2p-ca15-tc1.dtb make -C xen 
XEN_TARGET_ARCH=arm32 debug=y 
CROSS_COMPILE=/path/to/gcc-4.6.0-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-
