Koji build fails with weird "/bin/hostname not found" error

[Bernardo Innocenti]

Any idea why this build would fail?

  http://koji.fedoraproject.org/koji/taskinfo?taskID=309982

All I did was:
  koji build --scratch --arch-override=ppc dist-f9 'cvs://cvs.fedoraproject.org/cvs/pkgs?epiphany/devel#epiphany-2_21_4-1_fc9'

---cut---
ENTER do("bash -l -c 'rpmbuild -bs --target ppc --nodeps //builddir/build/SPECS/epiphany.spec'", '/var/lib/mock/dist-f9-build-98149-12971/root/', 0, True, 0, <mock.uid.uidManager object at 0xf75dfb10>, 425, 425, 'ppc', logger=<mock.trace_decorator.getLog object at 0xf7588030>)
run cmd timeout(0): bash -l -c 'rpmbuild -bs --target ppc --nodeps //builddir/build/SPECS/epiphany.spec'
