Bug#851524: Building armhf image fwith qemu fails at bootstrapping stage if firmware section enabled

[Jason Heeris <jason.heeris@gmail.com>]

Package: live-build
Version: 1:20161216

These two commands:

lb config \
  --archive-areas 'main firmware' \
  --distribution jessie \
  --architectures armhf \
  --bootstrap-qemu-arch armhf \
  --bootstrap-qemu-static /usr/bin/qemu-arm-static

sudo lb build 2>&1 build.log

...result in a build failure during bootstrapping, ending with:

P: Begin unmounting filesystems...
P: Saving caches...
/usr/bin/env: apt-get: No such file or directory

If I change the line:

--archive-areas 'main firmware'

...to...

--archive-areas 'main'

It works again.

This broke somewhere between version 1:20151215 and 1:20161216.

Full boot log is here: https://gist.github.com/detly/a0752dfafcdeb1eb8f2859c41a63fa32
