[Qemu-devel] [PATCH RFC 09/10] tests: tcg skip docker images we can't build

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

We have a mechansim (DOCKER_PARTIAL_IMAGES) for marking stuff that is
incomplete or won't build. We can use this to avoid attempting to
build them at the top of a check-tcg build. We need to move the
inclusion of docker/Makefile.include to ensure everything is resolved
by this point.

We also have to check this in tests/tcg/Makefile.include to cover the
case where users are building directly out of the target tree.
