# Due to make not wanting to run the same implicit rules twice on the same
# rule tree (implicit-rule recursion prevention, see "Chains of Implicit
# Rules" in GNU Make manual) we have to re-state the %.o and %.s patterns here
# for different directories, to handle cases where (say) a test relies on a
# compiler that relies on a .o file.
