[Qemu-devel] [PATCH v3 18/20] docker: add special handling for FROM:debian-%-user targets

["Alex Bennée" <alex.bennee@linaro.org>]

These will have been build with debootstrap so we need to check
against the debian-bootstrap dockerfile. This does mean sticking to
debian-FOO-user as the naming conventions for boot-strapped images.
The actual cross image is built on top.
