[Qemu-devel] [PATCH v2 11/21] docker: filter out linux-user builds for mingw

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

The recent change from TARGET_DIRS to TARGET_LIST (208ecb3e1) had the
effect of defaulting all docker builds to the current configured set
of targets. This is actually reasonable behaviour but does run into
problems if you have linux-user builds configured and you want to test
the windows cross builds. This commit fixes that by adding a
DOCKER_FILTER_TARGETS variable which is special-cased for mingw builds
so we don't pass the whole set down.
