FWIW, Sam had narrowed it down to:

[PATCH] relocatable kernel: Kallsyms generate relocatable symbols
Print the addresses of non-absolute symbols relative to _text
so that ld will generate relocations. Allowing a relocatable
kernel to relocate them. We can't actually use the symbol names
because kallsyms includes static symbols that are not exported
from their object files.
Add the _text symbol definitions to the architectures which don't
define it otherwise linker will fail.

[PATCH] relocatable kernel: Fix kallsyms on avr32 after relocatable kernel changes
o On some platforms like avr32, section init comes before .text and
not necessarily a symbol's relative position w.r.t _text is positive.
In such cases assembler detects the overflow and emits warning. This
patch fixes it.

but I personally still can't reproduce this. I even had the gcc-3.4.5
that's installed on my box, using defconfig just like you, and I can't
trigger this problem.
