Finish up support for i386-sysv4 (without shared libraries):
* ld.h (flag_is_weak): Define. * ldlang.c (print_symbol): Mention whether symbol is weak. (print_input_section): Print weak symbols as globals. * ldmain.c (refize): Do not zero out BSF_WEAK flag. (enter_global_ref): Do not warn if a weak symbol redefines a global symbol. Do not let a weak symbol redefine a common symbol. (enter_file_symbols): Treat weak symbols as global symbols. (subfile_wanted_p): Do not pull in an object file from a archive just to resolve an undefined weak symbol. * ldmisc.c (vfinfo): Don't needlessly malloc space after a fatal error; the error might be that malloc has run out of space. * ldsym.c (write_file_locals): Treat weak symbols as global. * configure.in (i[34]86-*-sysv4*, i[34]86-*-elf*): New targets; use i386-elf. * config/i386v4.mh: New file; set NATIVE_LIB_DIRS to /usr/ccs/lib. * config/i386-elf.mt: New file; set EMUL to elf_i386. * emulparams/elf_i386.sh: New file. * scripttempl/elf.sc: Use ${NOP} as filler (defaults to 0). * Makefile.in (NATIVE_LIB_DIRS): Define to be empty. (ALL_EMULATIONS): Add em_elf_i386.o. (GENSCRIPTS): Pass NATIVE_LIB_DIRS as sixth argument. (em_elf_i386.c): New target, like other em_*.c targets. ($(LD_PROG)): Pass $(CFLAGS) to $(CC). * genscripts.sh: Accept NATIVE_LIB_DIRS as sixth argument. If nonempty, and configured for native, add it to LIB_PATH.
