Can you look at the detailed build logs?

Often, when tests fail to build in our chroot, that=E2=80=99s because:

  =E2=80=A2 they refer to absolute file names (/usr/bin/modprobe,
    /lib/modules/xxx, etc.)

  =E2=80=A2 they have scripts with shebangs pointing to a file missing in t=
he
    chroot (#!/usr/bin/env, #!/bin/bash, etc.)

  =E2=80=A2 they attempt to do name lookups, which fails because the chroot
    lacks /etc/resolv.conf, /etc/services, etc.

If that is the case, a phase must be inserted before the =E2=80=98check=E2=
=80=99 phase
to adjust the faulty files.

HTH,
Ludo=E2=80=99.
