* 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.

-\c
-.B LDEMULATION\c
-\& controls some aspects of \c
-.B ld\c
-\&'s dominant
-personality.  Although \c
-.B ld\c
-\& is flexible enough to permit its use
-in many contexts regardless of configuration, you can use this variable
-to make it act more like one or another older linker by default.
-
-In particular, the value of \c
-.B LDEMULATION\c
-\& controls what default
-linker script is used (thereby controlling the default input and output
-formats; ; what default paths are searched for
-archive libraries; and in some cases whether additional linker script
-commands are available.
-
-Here is the current set of emulations available:
-
-.TP
-.B LDEMULATION=gld
-Emulate the older GNU linker.  When this emulation is selected, the
-default library search paths are
-.sp
-.br
-/lib
-.br
-/usr/lib
-.br
-/usr/local/lib/lib
-.br
-.sp
-
-The default output format is set to \c
-.B a.out-generic-big\c
-\&, and the
-default machine is the system's configured BFD default.
-
-.TP
-.B LDEMULATION=gld68k
-A variant of the \c
-.B gld\c
-\& emulation; only differs in specifically
-setting the default BFD machine as \c
-.B m68k\c
-\&.
-
-.TP
-.B LDEMULATION=gld960
-Emulate the Intel port of the older \c
-.B gld\c
-\& for the i960
-architectures.  The default library search paths are taken from two
-other environment variables, \c
-.B G960LIB\c
-\& and \c
-.B G960BASE\c
-\&.  The
-default architecture is \c
-.B i960\c
-\&.  The default output format is set
-to \c
-.B b.out.big\c
-\&, and in fact the default output file name (if
-\c
-.B \-o\c
-\& is not specified) is \c
-.B b.out\c
-\&, to reflect this variant
-format, for this emulation.
-
-This emulation can behave slightly differently depending on the setting
-of the \c
-.B ld\c
-\& compile-time switch \c
-.B GNU960\c
-\&.  If \c
-.B ld\c
-\& is
-compiled with \c
-.B GNU960\c
-\& defined, then an additional environment
-variable\(em\&\c
-.B GNUTARGET\c

-specifies some other default output format than \c
-.B b.out.big\c

-.B LDEMULATION=gldm88kbcs

-.B LDEMULATION=lnk960
-Emulate the Intel linker \c
-.B lnk960\c
-\&.  The default output format is
-\c
-.B coff-Intel-big\c
-\&.  With this emulation, \c
-.B ld\c
-\&
-supports the additional script commands \c
-.B HLL\c
-\& and \c
-.B SYSLIB\c
-\& for
-specification of library archives.  This is the only emulation with
-extensive support for the \c
-.B \-A\c
-\& (architecture) command-line option.
-By default, the architecture \c
-.B CORE\c
-\& is assumed, but you can choose
-additional features from the i960 architecture family by using one of
-the following with \c
-.B \-A\c
-\& (or by using the \c

-\c

-\& is also used if you've specified any of the architectures
-\c

-\&, \c
-.B SA\c
-\&, or \c
-.B CA\c

-
-Like \c
-.B gld960\c
-\&, this emulation uses additional environment variables
-to set the default library search paths.  Also like \c
-.B gld960\c
-\&, the
-behavior of this emulation is slightly different depending on whether
-\c
-.B ld\c
-\& itself was compiled with \c
-.B GNU960\c
-\& defined.
-
-If your \c
-.B ld\c
-\& was compiled with \c
-.B GNU960\c
-\& defined, the default
-paths are taken from all three of \c
-.B G960LIB\c
-\&, \c
-.B G960BASE\c
-\&, and
-\c
-.B I960BASE\c
-\&.  For the first two, paths you supply are automatically
-suffixed with `\|\c
-.B /lib/libcoff\c
-\|'; for the last, your path is
-automatically suffixed with `\|\c
-.B /lib\c
-\|'.
-
-If your \c
-.B ld\c
-\& was \c
-.I not\c
-\& compiled with \c
-.B GNU960\c
-\& defined,
-the default paths are taken from \c
-.B I960BASE\c
-\&, and \c
-.B G960BASE\c
-\& is
-only consulted if \c
-.B I960BASE\c
-\& is undefined.  In this case
-\c
-.B G960LIB\c
-\& is not used at all.
-
-.TP
-.B LDEMULATION=vanilla
-This is the least specific setting for \c
-.B ld\c
-\&.  You can set
-\c
-.B LDEMULATION=vanilla\c
-\& to disable emulation of other linkers.  This
-setting makes \c
-.B ld\c
-\& take the default machine from the BFD
-configuration on your system; \c
-.B a.out-generic-big\c
-\& is the default
-target.  No other defaults are specified.
