From c812942fc5ee69a02640b6f12f6e238cfc2eb004 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Hack to cut down compilations needed for minimal-bfd:

	* Makefile.in (ALL_MACHINES): Renamed from BFD_MACHINES.
	(ofiles): New target.  Build a list of unique file names, in case
	any got duplicated.
	(TARGETLIB): Use list of files from ofiles.
	* configure.in: Set BFD_MACHINES and BFD_BACKENDS depending on
	minimal-bfd flag and target makefile frag contents.
