Comment 4 for bug 1597349

It appears the problem relates to where module-assistant is looking for build scripts.

Build break error relates to...

   /bin/bash: /build/xtables-addons-smmDiF/xtables-addons-2.10/build-aux/missing: No such file or directory

This is correct, as there's no /build/... directory generated by module-assistant.

And several .../build-aux/missing files turn up via locate...

locate /build-aux/missing | egrep -v -e /lxc/
/usr/share/libtool/build-aux/missing
/usr/src/modules/xtables-addons/build-aux/missing
/usr/src/xtables-addons-2.10/build-aux/missing
/var/lib/dkms/xtables-addons/2.10/build/build-aux/missing

So likely fix is for module-assistant to look for build scripts in correct directory.
