	* config.gcc: Don't default xmake_file to ${cpu_type}/x-${cpu_type}.
	Remove references to deleted files.
	(*-*-openbsd): No need to override xmake_file.
	(*-*-sysv4): Treat like *-*-sysv.

	* configure.in: Probe for ldopen in various places, and set up
	collect2 to be linked with them if found.
	Don't dink with Windows registry stuff unless $host_os is a
	Win32 os name.  Check to see if we need -ladvapi32.
	* configure: Regenerate.

	* Makefile: Get rid of CLIB and HOST_CLIB.
	Substitute in COLLECT2_LIBS and link collect2 against its contents.
	* build-make: Get rid of HOST_CLIB.

	* config/a29k/x-unix, config/alpha/x-osf, config/i386/x-aix,
	config/i386/x-osfrose, config/m68k/x-dpx2, config/mips/x-iris3,

	config/mips/x-sysv, config/rs6000/x-aix31, config/rs6000/x-aix41,
	config/rs6000/x-rs6000: Delete.

	* config/i386/x-cygwin, config/m68k/t-aux, config/mips/x-iris:
	Don't set CLIB.

	24 x-host fragments remain, 0 x-cpu, 3 top level.
