* 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.
* ldmain.h (ld_sysroot): New extern.
* emultempl/elf32.em: Use NATIVE and USE_LIBPATH instead of
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.
* emulparams/elf32ppc.sh: Likewise.
* emulparams/elf64_s390.sh: Likewise.
* emulparams/elf64_sparc.sh: Likewise.
* emulparams/elf64ppc.sh: Likewise.
* emulparams/elf_x86_64.sh: Likewise.
