When trying to change the patch accordingly, I discovered that
the 'linux-kernel-headers' package does not install the x86_64 kernel 
headers on i386. The x86_64 kernel headers will be necessary to compile
the 64bit x86_64 version of libc6 on i386. In the opposite case, the
i386 kernel headers are already being installed on amd64 by the current
sid version of 'linux-kernel-headers'.

I just filed a wishlist bug on 'linux-kernel-headers' to the BTS with a 
patch that installs the x86_64 linux kernel headers on i386 in the 
'/usr/include/x86_64-linux' directory.

Maybe the patch in my previous email which handles just 
the amd64/libc-i386 case could be applied to glibc first? 
The i386/libc-amd64 could then be added later when
an amended 'linux-kernel-headers' packages with the x86_64 headers
becomes available on i386.
