Jailhouse is a partitioning Hypervisor based on Linux. It is able to run
bare-metal applications or (adapted) operating systems besides Linux.
For this purpose, it configures CPU and device virtualization features
of the hardware platform in a way that none of these domains, called
"cells" here, can interfere with each other in an unacceptable way.

 I applied to master, but with a number of changes.

 First of all, for 32-bit ARM, jailhouse uses instructions from the armv7ve ISA.
Since we don't have a Config.in symbol to represent this yet, I've just removed
32-bit ARM as one of the supported architectures for now.

                   ^^^^^^^^^^^^^^^^^^^^^
 This is what I removed.

 The architecture dependency needs to be repeated here.

 We don't give comments for architecture dependencies, since there's nothing the
user can do about it.

 Do those helper scripts really only work with python2.7, not with python3?

 I have moved this into the condition below.

i.e. here:
JAILHOUSE_DEPENDENCIES += host-python-setuptools

 We usually define a helper variable for this, but we also sometimes use it like
this, so I've kept it.
