* ldfile.c (ldfile_open_command): Don't try .ld extension. It wasn't documented (or likely used) and wastes time.

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.
