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

* 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.
