compiling nvidia driver, error when ld obj from elf64-x86-64 to elf32-i386

Reproducible: Always

Steps to Reproduce:
1. install  64-bits OS 
2. download the nvidia-drivers-190.42-r3.ebuild
3. emerge nvidia-drivers

Kernel: linux-2.6.31-gentoo-r6
ebuild: nvidia-drivers-190.42-r3.ebuild
uname -a: Linux 2.6.32-24-generic #39-Ubuntu SMP Wed Jul 28 05:14:15 UTC 2010 x86_64 GNU/Linux

I want to compile the nvidia.ko for my 32-bits X86 based target board. So I try to emerge the nvidia, I can compile the files, but when we try to ld the obj, there's error, it says:"i686-pc-linux-gnu-ld: Relocatable linking with relocations from format elf64-x86-64 (/build/x86-generic/tmp/portage/x11-drivers/nvidia-drivers-190.42-r3/work/NVIDIA-Linux-x86-190.42-pkg0/usr/src/nv/nv.o) to format elf32-i386 (/build/x86-generic/tmp/portage/x11-drivers/nvidia-drivers-190.42-r3/work/NVIDIA-Linux-x86-190.42-pkg0/usr/src/nv/nvidia.o) is not supported".

I type the i686-pc-linux-gnu-ld --help, they told me the tool support both elf32 and elf64, but why can mixed link these kinds of obj together?


Actual Results:  
i686-pc-linux-gnu-ld complain it can not do these job.

Expected Results:  
We can use i686-pc-linux-gnu-ld to link both 32-bits obj and 64bits obj into one obj.

Actually I run on the ChromesOS which is gentoo customize OS, HOST is ubuntu-64bits.  CROSS_COMPILE is i686-pc-linux-gnu-ld, HOSTCC=x86_64-pc-linux-gnu-gcc.

please not add in the future arch teams, it is wrangler's job
