* configure.in: Call AC_CONFIG_HEADER. Substitute

	HOST_64BIT_LONG.  Check that various header files exist.  Check
	that fcntl exists.  Call BFD_BINARY_FOPEN.  Check whether malloc
	and/or free need to be declared.  Don't make a link to sysdep.h.
	Define TRAD_HEADER for various hosts.
	* configure: Rebuild.
	* configure.host: Don't set my_host.  Add definitions taken from
	host header files for various entries.  Remove entries which now
	do nothing.
	* acconfig.h: New file.
	* config.h.in: New file, built by autoheader.
	* sysdep.h: New file.
	* Makefile.in (do_distclean): Don't remove sysdep.h.
	(RECONFIG): Remove.
	(LOCAL_H_DEPS): New variable.
	($(BFD_LIBS)): Use $(LOCAL_H_DEPS) rather than libbfd.h and
	$(RECONFIG).
	($(BFD_MACHINES), $(BFD_BACKENDS)): Likewise.
	($(OPTIONAL_BACKENDS)): Likewise.
	(stmp-bfd.h): Just substitute for BFD_HOST_64BIT_LONG, rather than
	looking through sysdep.h.
	* bfd-in.h (BFD_HOST_64BIT_LONG): Define; set by Makefile.
	(BFD_HOST_64_BIT): Define based on BFD_HOST_64BIT_LONG.
	(fprintf_vma, sprintf_vma): Likewise.
	(int64_type, uint64_type): Don't define.
	* bfd-in2.h: Rebuild.
	* archures.c, bfd.c, srec.c: Include <ctype.h>.
	* elfcore.h: Check HAVE_SYS_PROCFS_H rather than HAVE_PROCFS.
	* lynx-core.c: Include stuff from old hosts/lynx.h.
	* opncls.c (bfd_fdopenr): Check HAVE_FNCTL and defined (F_GETFL),
	rather than NO_FCNTL.
	* targets.c (bfd_target_list): Check HOST_HPPAHPUX and ! __STDC__
	rather than NATIVE_HPPAHPUX_COMPILER.
	* trad-core.c: Don't include <errno.h>.  Include TRAD_HEADER if it
	is defined.
	* hosts/*.h: Remove all header files which merely include,
	declare, and define things.  Leave header files which define
	information needed by trad-core.c.
