against Linux shared libraries.

* emulparams/i386linux.sh (TEMPLATE_NAME): Define as linux.
* ld.h (args_type): Add new field interpreter.
* lexsup.c (parse_args): Add dynamic-linker to longopts, and
handle it.
* ldmain.c (main): Initialize command_line.interpreter to NULL.
* emultempl/elf32.em (gld${EMULATION_NAME}_before_allocation): Get
the ELF backend to return the .interp section. If
command_line.interpreter is not NULL, set the contents of .interp
to it.
* ld.texinfo: Mention -dynamic-linker.
* aout.sc: Don't define __DYNAMIC here. Add new sections used by
shared library support code.

* ldmain.c (main): Initialize config.dynamic_link to false. Warn
on attempts to use -r with -relax, -call_shared or -s.
* lexsup.c (longopts): Separate OPTION_CALL_SHARED from
OPTION_NON_SHARED. Add OPTION_IGNORE. Adjust macro values
accordingly. Add "dy" and "non_shared" options. Change "Qy" to
OPTION_IGNORE for now. Handle OPTION_CALL_SHARED and
OPTION_NON_SHARED by setting dynamic_link field accordingly.
Handle OPTION_IGNORE by ignoring it. Clear dynamic_link field for
-r and -Ur.
* ldfile.c (ldfile_open_file): If config.dynamic_link is true, try
opening a file with a .so extension first.
* emultempl/elf32.em: New file.

(DATA_PLT): Define.
* emulparams/elf_i386.sh (TEMPLATE_NAME): Define as elf32.
* scripttempl/elf.sc: Add placement for new dynamic sections.
Don't use CREATE_OBJECT_SYMBOLS. Define _etext, _edata and _end
outside of any section. Don't use ALIGN(8); just let one section
VMA follow another. Put .dynbss in .bss. Don't mention debugging
sections; they'll be handled correctly anyhow.
* Makefile.in (eelf_i386.c): Depend upon elf32.em, not generic.em.
* emultempl/gld960.em, emultempl/gld960c.em, emultempl/lnk960.em,

to handle new filenames.

(hppaelf_finish): Reenable code. Do not pass symbols
down to hppa_look_for_stubs_in_section.
Add comments in several functions as to their purpose and
how they function (or my current best guess). Clean up horrible
spacing and indention that never should have been accepted in the
first place. Add FIXMEs for issues which need to be resolved.
Disable linker-stub generation until it gets fixed. This allows
the linker to at least work on simple code for testing purposes.
it via hppaelf_finish). Prototype moved into ldlang.h.
(lang_process): Move problematic extra call to lang_size_sections
into the PA ELF specific code.
* emultempl/hppaelf.em (hppaelf_finish): Extra call to
lang_size_sections moved here.

(file): Instead of command line, recognize an
input type indicator, then use the nonterminal for that type.
(defsym_expr): New nonterminal from code formerly in command_line.
* ldlex.h: Declare parser input type enum and variable.
Don't declare parse_line.

At start of yylex, return input state token if at start of input.
(lex_redirect): Don't need to set yyout.
(ldlex_command): Function removed.

redirections and call yyparse directly.

"command line".
* lexsup.c: Remove #if 0'd code.
(parse_line): Function removed.
(parse_args): Rewrite to use getopt_long_only.
(set_default_dirlist): New function from code formerly in
ldgram.y:command_line.
(set_section_start): New function.
* emultempl/generic.em, emultempl/gld960.em, emultempl/hppaelf.em,
emultempl/lnk960.em, emultempl/m88kbcs.em: Don't enclose
compiled-in link scripts in "{" and "}", as the grammar no longer
wants them to be.
with only one character.
(lprefix_len): Set default to one.
* ldmain.h (lprefix_len): Declare.
* ldsym.c (write_file_locals): Use strncmp rather than a character
comparison for lprefix.

hppaosf_create_output_section_statements): New functions in
support of linker stub generation.
(ld_hppaosf_emulation): Redefine to include new
emulation-specific routines.
* emultempl/hppaosf.em (ld_hppaosf_emulation): Correct name for PA
ELF emulation is "elf32-hppa" not "elf-big".
(hppaosf_before_parse): Remove unneeded processing of environment variables.
* scripttempl/hppaosf.sc: Include .hppa_linker_stubs sections in
.text segment of output file.
* emulparams/hppaosf.sh (OUTPUT_FORMAT): Use elf32-hppa.
It wasn't documented (or likely used) and wastes time.

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.

try with the extension even if -v or -V was given.
