+# Some functions are duplicated across subdirs, and when you pass $(AR)
+# the same object file more than once, it'll add it to the archive multiple
+# times (boo!). So what we do here is:
+# - import all the objects (thus we may have dupes)
+# - delete all the dupes
+# - re-import certain objects based upon preference
+# - the sysdeps dir should override all other symbols for example
+# We need to use shell globbing with obj.* because if we use make's wildcard,
+# the wildcard will be evaluated when `make` is run instead of when the make
+# target is evaluated. That means if you run `rm obj.* ; make`, the wildcard
+# will evaluate to no files :(.
