(gld${EMULATION_NAME}_try_needed): Call stat_needed to make sure
that the file has not already been included under another name.
(gld${EMULATION_NAME}_stat_needed): New static function.
* configure.tgt: Add i386lelf to targ_extra_emuls for
i[345]86-*-linuxaout* and i[345]86-*-linuxoldld. For
i[345]86-*-linux*, set targ_emul to i386lelf, and add elf_i386 to
targ_extra_emuls.
* emulparams/i386lelf.sh: New file, a copy of elf_i386.sh.
* emultempl/elf32.em: If TARGET_IS_i386lelf, use autoconf
recommended mechanism to define DIR and struct dirent.
(libcmp): New static function use only when TARGET_IS_i386lelf.
(gld${EMULATION_NAME}_open_dynamic_archive): Likewise.
* Makefile.in (ALL_EMULATIONS): Add ei386lelf.o
(ei386lelf.c): New target.
* ld.h (args_type): Add new field interpreter.
* lexsup.c (parse_args): Add dynamic-linker to longopts, and
handle it.
* ldmain.c (main): Initialize command_line.interpreter to NULL.
* emultempl/elf32.em (gld${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.
* ld.h (ld_config_type): Add field dynamic_link.
* 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.
* emulparams/elf32_sparc.sh (TEXT_START_ADDR): Change to 0x10000.
(NONPAGED_TEXT_START_ADDR): Likewise.
(TEMPLATE_NAME): Define as elf32.
(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.
