[Qemu-devel] [RFC PATCH 3/3] tests/vm: expose BUILD_TARGET, TARGET_LIST and EXTRA_CONFIGURE_OPTS

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

Now the underlying basevm support passes these along we can expose
some additional variables to our Makefile to allow more customised
tweaking of the build. For example:

  make vm-build-freebsd TARGET_LIST=aarch64-softmmu \
    EXTRA_CONFIGURE_OPTS="--disable-tools --disable-docs" \
    BUILD_TARGET=check-softfloat
