+# TCG tests
+#
+# 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 the following:
+#
+#   CC - the C compiler command
+#   EXTRA_CFLAGS - any extra CFLAGS
+#   BUILD_STATIC - are we building static binaries
+#
+# By default all tests are statically compiled but some host systems
+# may not package static libraries by default. If an external
+# cross-compiler can only build dynamic libraries the user might need
+# to make extra efforts to ensure ld.so can link at runtime when the
+# tests are run.
+#
+# We also accept SPEED=slow to enable slower running tests
+#
+# We also expect to be in the tests build dir for the FOO-(linux-user|softmmu).
