First, there are a number of features in newer QEMU that will allow us
to test a wider range of platforms, so we want to use at least v2.8.0.
Second, making use of a PPA for QEMU fails from time to time.  So we
change to checking out and building a copy of QEMU when we know that we
are going to use test.py and need QEMU to be installed.  This adds
around 4 minutes per test.py job that we run.

you could speed up git clone:
git clone --depth 1 --single-branch --branch v2.8.0-rc3 git://git.qemu.org/qemu.git /tmp/qemu
pushd /tmp/qemu
git submodule update --init --recommend-shallow --reference /tmp/dtc dtc
Because we already cloned dtc in the install steps, we could use it as reference repository.
BTW: you should consider adding "--single-branch --branch master" to the other clone tasks too.
I might do this in a follow up but this is an area where we're talking
about seconds of time vs making things start to be harder to read.
Thanks!
