Your arch/arm/boot/Image is ~3GB, right? I had that too and it drove  
me nuts for several hours. The explanation is that recent versions  
(2.18) of binutils get confused about .note.gnu.build-id sections and  
produce garbage then. The solution is to eigther use 32bit-only  
userspace binaries to build your toolchain and kernel or to apply the  
following patch to your kernel tree.

rp-2.6.22%2B2.6.23-rc4/binutils-buildid-arm.patch?rev=2726&view=markup

Hope that helps.

Greets,
