[Qemu-devel] [PULL v2 50/57] tests: add top-level make dependency for do

Subject: [Qemu-devel] [PULL v2 50/57] tests: add top-level make dependency for docker builds
Date: Thu, 21 Jun 2018 07:25:58 +0100

One problem with satisfying your docker dependencies in a sub-make it
you might end up trying to satisfy the dependency multiple times. This
is especially a problem with debian-sid based cross compilers and CI
setups. We solve this by doing a docker build pass at the top level
before any sub-makes are called.

We still need to satisfy dependencies in the Makefile.target call so
people can run tests from individual target directories. We introduce
a new Makefile.probe which gets called for each PROBE_TARGET and
allows us to build up the list. It does require multiply including
config-target.mak which shouldn't cause any issues as it shouldn't
define anything that clashes with config-host.mak. However we undefine
a few key variables each time around.
