Can you use a _files prefix to let gyp do this transform for you?

If so, I couldn't get it to work. The problem is we need <(PRODUCT_DIR) to be an
absolute path. Dumping that into a var with any of the special prefixes here
didn't help:

+       '--build-temp', temp_path],
+      cwd=os.path.dirname(os.path.abspath(__file__)))
+
+    # Since setup just copies the Python files over, timestamps remain unchanged
+    # and GYP gets confused about whether it has already generated psutil. Touch
+    # all the Python related outputs to put GYP's mind at ease.
