Ok, this changeset:

changeset:   11223:a4550b7488400c44a9f27c92115c8e364493837a
user:        Ian Campbell <ian.campbell@xxxxxxxxxxxxx>
date:        Tue Aug 22 14:20:43 2006 +0100
files:       linux-2.6-xen-sparse/arch/i386/kernel/vmlinux.lds.S
[LINUX] Support creating ELF note segments in the kernel ELF image.

dies, while the previous one
(11222:cd4e7ace4e58d9e35c08ccaa4677c6b6d0cf137b) works.

Looking at the patch, I thought it might be a toolchain issue, so I
tried with two toolchains, both of which displayed the same results.

(cross compiling i386 to x86-64)
gcc version 3.4.4
ld version: 2.15

(native compilation on x86-64)
gcc version 3.3.3 (SuSE Linux)
GNU ld version 20040303 (SuSE Linux)
