- Add Linux style directory searching.
- * 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.
-
* Makefile.in (config.status): Depend upon configure.tgt.
* ldemul.h (ldemul_set_symbols): Declare.
