+	* Makefile.am (SUBDIRS): Change the order of the directories so
+	that a directory will be made after the dependent directories
+	are made. `grub' depends on `stage2', and `docs' depends on
+	`grub'. Do not make in parallel.
+	* docs/help2man: Copied from help2man-1.012, which contains my
+	previous change.
+	* docs/grub.8: Regenerated.
