[Qemu-devel] [PATCH v2 35/43] tests/tcg/Makefile: update to be called from Makefile.target

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

This make is now invoked from each individual target make with the
appropriate CC and EXTRA_CFLAGS set for each guest. It then includes
additional Makefile.targets from:

  - tests/tcg/multiarch (always)
  - tests/tcg/$(TARGET_BASE_ARCH) (if available)
  - tests/tcg/$(TARGET_NAME)

The order is important as the later Makefile's may want to suppress
TESTS from it's base arch profile. Each included Makefile.target is
responsible for adding TESTS as well as defining any special build
instructions for individual tests.

Signed-off-by: Alex Bennée <alex.bennee@linaro.org>

v2
  - cleaner approach to include sub makefiles
  - move TESTS/VPATH manipulation into sub-makefile
  - avoid double inclusion when TARGET_BASE_ARCH==TARGET_NAME

+# These are complicated by the fact we want to build them for guest
+# systems. This requires knowing what guests we are building and which
+# ones we have cross-compilers for or docker images with
+# cross-compilers.
+#
+# The tests themselves should be as minimal as possible as
+# cross-compilers don't always have a large amount of libraries
+# available.
+#
+# We only include the host build system for SRC_PATH and we don't
+# bother with the common rules.mk. We expect CC/LD to have been set for
+# us from the parent make as well as being passed EXTRA_CFLAGS.
+#
+# We also expect to be in the tests build dir for the FOO-linux-user.
