If you want to show include directories, you should show cpp -v,
not gcc -v.  But it's obvious why this doesn't work since you're
telling it to build for amd64, not for x32.

That is clearly not what you want.  Your libc dev package at least
doesn't match that.  Please note that it's calling gcc with -m64,
but you don't have the headers for that.

Why are you reporting something about the upstream source to
Debian while the Debian package build fine?  It has an debian-x32
target that uses -mx32.

I'm not sure there is a sane way to make config auto detect that
you want x32.  You should at least make uname -m report x32
instead of x86_64.

If you remove the -m64 it might also just work for you, but I have
no idea if it requires the -mx32 or not.
