* ldfile.c (ldfile_open_command): Don't try .ld extension.

	It wasn't documented (or likely used) and wastes time.
	(try_open): If EXTEN is empty, don't try it.

	* ldctor.c, lderror.c, ldexp.c, ldfile.c, ldindr.c, ldlang.c,
	ldlex.l, ldmain.c, ldmisc.c, ldsym.c, ldver.c, ldwarn.c,
	ldwrite.c, lexsup.c, mri.c, relax.c: Replace DEFUN macro calls
	with normal function declarations.

	* Move *.em to emultempl/*.em.  Move *.sh to emulparams/*.sh.
	Move *.sc-sh to scripttempl/*.sc.
	* {emultempl,emulparams,scripttempl}/README: New files.
	* sh.em, st2000.em, z8ksim.em, h8300hms.em, h8500hms.em: Files
	removed, replaced with generic.em.
	* h8300.sh, h8500.sh, h8300.sc, h8500.sc: Renamed from
	 h8[35]00hms.s[ch].  Change their contents to omit the "hms".

	* *.em (*_get_script): Return script name instead of script contents.
	* ldlang.c (lang_process): Change caller.

	* ldlex.l, ldgram.y: Recognize -m option.
	Check for input files after *all* options in grammar.
	* ldmain.c (main): Check for -m options.  Add default directory
	for -m.

	* mkscript.c: File removed.
	* genscripts.sh: Take two more parameters, tooldirlib and libdir,
	to add to the default LIB_PATH.
	Look for input files in the new subdirectories.
	Create the scripts in emulations subdirectory and don't filter
	them through mkscript.
	* configure.in: Make the emulations subdirectory.

	* Makefile.in: Account for all of the above changes.
	Remove unused .SUFFIXES.  Get libgcc.a path with gcc
	-print-libgcc-file-name instead of $(libdir)/libgcc.a.
	Put CFLAGS last in the compilation rules.
	Add -I../bfd to INCLUDES so sysdep.h is found.

	* ldfile.c (try_open): If opening without the extension fails,
	try with the extension even if -v or -V was given.
	had_script is imported (from ldgram.y), not exported.
