I build my kernel in a different directory to where the sources are
stored and I get:

make[7]: *** No rule to make target `/home/tbm/kernel/linux-2.6-2.6.32~rc6/debian/build/source_armel_none/arch/arm/lib/lib1funcs.o', needed by `arch/arm/boot/compressed/vmlinux'.  Stop.

The following patch makes it compile for me:
