# For metadata output, a temporary directory will be created to hold the temporary
# metadata file. But when output is stdout, the temporary directory will be located
# in the same place as $(SRC), which is mounted as read-only in the tests. Thus as
# a workaround, $(SRC) is copied to the test output directory $(OUT) and we compile
# it there.
