* aclocal.m4: New file.
* configure: New file, built by autoconf.
* acconfig.h: New file.
* config.h.in: New file, built by autoheader.
* Makefile.in: Various changes for new configure script. Also:
(PROGS): Remove $(SYSINFO_PROG).
(ALL_CFLAGS): Remove $(TDEFINES).
(version.o): Use $(ALL_CFLAGS).
(cplus-dem.o, dlltool.o, nlmconv.o): Likewise.
(sysdump.o): Depend upon bucomm.h and config.h.
(srconv.o, arsup.o, strings.o): Depend upon config.h.
(filemode.o): Don't depend upon ../bfd/sysdep.h.
(bucomm.o): Depend upon config.h, not ../bfd/sysdep.h.
(size.o, objdump.o, nm.o, ar.o, objcopy.o): Likewise.
(nlmheader.o, nlmconv.o): Likewise.
(distclean): Don't remove sysdep.h.
* bucomm.h: Include "ansidecl.h", <stdio.h>, and "config.h".
Include "fopen-same.h" or "fopen-bin.h", based on
USE_BINARY_FOPEN. Include <errno.h>, and declare errno if it is
not a macro. Include <unistd.h>, <string.h>, <strings.h>,
<stdlib.h>, and <fcntl.h> if they are present. Declare strchr,
strrchr, and strstr if no string header file exists. Include
<sys/file.h> if it exists and <fcntl.h> does not. Define
O_RDONLY and O_RDWR if necessary.
* ar.c: Don't include "sysdep.h". Do include <sys/types.h> and
<sys/stat.h>. Use HAVE_GOOD_UTIME_H rather than POSIX_UTIME. Use
HAVE_UTIMES rather than !USE_UTIME. Don't include <errno.h>, and
don't declare errno.
* arsup.c: Don't include <sysdep.h>.
* bucomm.c: Don't include "sysdep.h". Include <stdio.h>,
<sys/types.h>, and <sys/stat.h>. Include <time.h> if it defines
time_t. Define time_t if necessary.
* coffdump.c: Don't include "sysdep.h".
* coffgrok.c, filemode.c, nlmconv.c, size.c: Likewise.
* srconv.c, strings.c: Likewise.
* nm.c: Don't include "sysdep.h". Don't try to define HAVE_SBRK.
* objcopy.c: Don't include "sysdep.h". Include <sys/types.h> and
<sys/stat.h>.
(simple_copy): Use creat rather than assuming that O_CREAT is
defined.
* objdump.c: Don't include "sysdep.h". Use
NEED_DECLARATION_PRINTF rather than !FPRINTF_ALREADY_DECLARED.
* sysdump.c: Include "bfd.h" and "bucomm.h". Don't include
"sysdep.h" or <stdlib.h>.
(dump_symbol_info): Rename from symbol_info. Change all callers.
