[OpenAFS] Cross compiling openafs modules in Debian stable works with 1.4.7 but fail with 1.4.11 or 1.4.12

I used to cross compile openafs modules to amd64/x86_64 linux kernel
from a i386 userland.  I am using the kernel-package command to
produce a debian package with the openafs modules.  The last time I
compiled new modules was with openafs 1.4.7, for kernel 2.6.26.

Now I try to do the same with openafs modules 1.4.11 or 1.4.12 for
Linux kernel 2.6.26. But it fails with what seams to be typical cross
compiling problems.  I Have looked into the code and logs from
openafs-modules-source and kernel-package.  And I found nothing wrong,
or different from openafs 1.4.7.  The proper flags for cross-compiling
seams to be correct, the generated .o files are for x86_64.  The full
error messages are in the end of the email.

The initial error message is:

My setup is Debian 5.0/lenny i386 running the amd64 kernel from
Debian.  uname -a

Linux copernico 2.6.26-2-amd64 #1 SMP Tue Mar 9 18:27:05 UTC 2010 x86_64 GNU/Linux

I am compiling the sources in the package openafs-modules-source.
Version  1.4.7.dfsg1-6+lenny2 from Debian stable works, versions
1.4.11 and 1.4.12 from backports.debian.org don't cross-compile for amd64.
