* Makefile.am (eelf32iq10.c): Fix tab/whitespace mixup.

	* Makefile.am (ldmain.o): Add @TARGET_SYSTEM_ROOT_DEFINE@.
	(GENSCRIPTS): Add @use_sysroot@.
	* Makefile.in: Regenerated.
	* configure.host: Move setting of NATIVE_LIB_DIRS to...
	* configure.tgt: ... here.  Use ${target} instead of ${host}
	for NATIVE_LIB_DIRS.
	* configure.in: Add --with-sysroot.
	* configure: Regenerated.
	* genscripts.sh: Accept use_sysroot option.  Set new variables
	NATIVE and USE_LIBPATH.  Prepend "=" to directory names if
	$use_sysroot.  Don't search $tool_lib if $use_sysroot.
	* ldfile.c (ldfile_add_library_path): Handle leading '='.
	* ldmain.c (TARGET_SYSTEM_ROOT): Define if not defined.
	(ld_sysroot): New variable.
	(main): Initialize ld_sysroot.

	searching $EMULATION_LIBPATH.
	(gld${EMULATION_NAME}_add_sysroot): New function.
	(gld${EMULATION_NAME}_check_ld_so_conf): Use it.  Honor ld_sysroot.
	(gld${EMULATION_NAME}_after_open): Likewise.  Only search
	environment variables if $NATIVE.
	* ld.texinfo (Options): Mention "=" prefix in the description of -L.
	* NEWS: Mention --with-sysroot.

	* emulparams/elf32bmipn32-defs.sh: Set NATIVE and LIBPATH_SUFFIX
	instead of setting LIB_PATH.
