Ok, changed.

Also changed.

This is not the include path of the kernel headers, but the place were
to install the glibc headers. Look at i386.mk or hppa.mk.
Not that I have changed this directory to /usr/include/i386-linux-gnu,
to be consistent with hppa and i386.

This comes from i386.mk that I used as a base for amd64.mk. I have
successfully rebuilt it without this part, so I have removed it from my
patch.
Please find attached a new patch, that uses /lib32 and /usr/lib32. There
is a lot of difference from the previous patch, so don't hesitate to
comment it. I know there is a missing conflicts with the current version
of ia32-libs, I am currently looking for a way to do it cleanly.
