From f7ed9c569b2e429563c6ac0021d9599a09741355 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Improve top-level Makefile rules

Use automake's '+=' to simplify include_HEADERS rules.  Move most
EXTRA_DIST files to noinst_HEADERS, eliminating duplication of headers
listed by include_HEADERS.  Add MIPS and PPC32 headers that were not
being distributed previously.
