Finish up support for i386-sysv4 (without shared libraries):

Browse source 
* 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.
