I tracked this down as well now, and it's also a problem on my local machine, your patches are fine. In order to debug the other problem, I was building with "make LD=/home/arnd/..../ld" to try out different versions of the linker, and that caused the "LD += -EB" line from arch/arm/Makefile to be ignored. We should probably override LDFLAGS rather than LD (and AFLAGS instead of AS) for big-endian builds, but that is unrelated to your work.
