Subject: build: Build docs from the top-level Makefile.

This undoes commit 575ed8d ("doc: Create own Makefile.am in subdirectory."),
and fixes a bug whereby "make pdf" or "make ps" wouldn't do anything.

* doc/Makefile.am: Remove.
* doc.am: New file.  Use `-local' rules to build the image.
* Makefile.am: Include it.
* configure.ac: Use `-Woverride' to avoid undesired overridding of
  Automake rules.
