I looked into this build error.

This happens depending on 'debian/arch'.

My host machine is x86_64.


When I run "make defconfig; make bindeb-pkg",

$ cat debian/arch
amd64



When I run "make allnoconfig; make bindeb-pkg",

$ cat debian/arch
i386



$ head -n 6 debian/control

After I applied the following patch,
I was able to build "make allnoconfig; make bindeb-pkg".
