c92d9ee900 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
* configure.in: Set ALL_OBJ_DEPS in output Makefile.

Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu> (Charles Bailey):

from other directories into objects in the current directory, and specify PSECT
attributes explicitly to linker.  Also added missing label.

non-local object files, instead of listing them here.

	* binutils.all/objdump.exp: Add more wildcards to list of
	single-letter options in pattern for usage message.

	* binutils.all/nm.exp: Deleted debug-symbols test, since it only
	works for a.out/stabs systems.  Fixed regexps to make underscores
	optional, since some C compilers don't prepend them.  Deleted
	check for foo.o symbol, since again some systems don't generate
	it.
