That made xapt create the packages indeed, thanks.

It isn't that long. :-)  However, the man page also mentions that I
should have the arch listed in my foreign architectures, but on my
system, dpkg --print-foreign-architectures does not give any output.
This doesn't seem to be a problem, though.  Do I need to worry about
this?

What do you mean with "move the files properly"?  I just removed all
symlinks, deinstalled all packages (which were mostly from the emdebian
archive) and installed packages created by xapt.  However, there doesn't
seem to be a difference and the compile fails again on stubs-n32_hard.h.

Do you suggest I should move the files to the other directory manually?

I'm sure that will make this part work again, and I will again be stuck
at the linker errors.

Thanks,
